Ed Tech(Educational Technologies) trends in 2021 and future

We are often told that change is the only constant. And you get to experience it multiple times in your life. Everything has changed since the beginning. Just take a look at current industries, be it automobile or even IT. 

Every sector has evolved since it was first started. I mean, just look at the means of communication, we used to write letters and now, all of us own mobile phones and can connect with anyone from all over the world. 

Many people claim that currently, we are in the middle of the fourth industrial revolution. Ye, we see technology change at an enormous rate, and it affects all of our lives drastically.

The introduction of the world wide web and the change it has brought have transformed the world. Every aspect of our lives has evolved unrecognizably, and it is for the best. From our economies to the supply of goods, everything has evolved. 

We now pay with UPI and book taxis on our phones. The electric car has become the future, and it is safe to say that we have come a long easy from bullock carts. Change can be seen in every sector. But the one sector that not only has evolved but is responsible for affecting every other sector is the education sector. 

If you pay attention to it, you will see that the factor responsible for all the transformations we see in the current world was because of extensive research and study. So, the pivotal changes that have directly influenced the other sectors are the education sector. 

Our classrooms and modes of teaching continue to upgrade and evolve with every passing year. They keep up with the technological advancements and use the new trends in technology to make learning more fun and engaging. Everything has seen progress from the subject matter to how things operate in the actual classroom. 

The educational sector has reported positive and exponential changes in every part of the world. From primary education to the university level, every tier has been incorporating new methods and techniques in teaching. 

Even the studying material is being updated regularly to match up with the current trends. Colleges now offer professional degrees in more fields. That makes it easier for the students to pursue their goals and get professionally trained by the best in class methods and faculty. 

With the fierce competition in the industry, it is imperative to change the way we prepare the candidates. The study material and the teaching methods should be tailor according to the needs of the industry. The education sector is evolving with each passing year, and in this article, we have listed the current changes that we saw take place in 2021. 

1. Upskilling technology across domains

People often pity the technology and human labor against each other. We see the trend where choosing one can result in neglecting the other. We use the technology to replace humans. But the original purpose of technology is to support humans, help them work optimally, and give the best results. 

Using the two in sync can result in optimum results. Once, the fear of technology is eliminated. The focus can shift on using the two together and enhance the level of the educational sector.

Upskilling technology has emerged as one of the top technological trends in 2021. Industries are heading towards workflow automation, and the human interface is important for a smooth workflow. 

Therefore the businesses are adopting cloud convergence, to help the candidates build cloud-based technological skills. These skills help the candidates become tech-savvy and increase the chances of their employment. 

Cloud-related technology training programs are increasingly adopted by the latest institutions. These programs exist to help the candidates match up with the expectation of employers. These programs are becoming increasingly popular in both online educational courses and campus-based institutions. 

Many online institutions are launching their services to help the candidates learn through their effective courses. The candidates can learn not only machine learning but also the effective deployment of using cloud infrastructure. 

These courses exist to help the learners access resources and a competent faculty. And master the skills that are high in demand and can help them land their desired job. 

2. Polishing of soft skills via curriculum

Along with the subject-based learning, and skills oriented learning methods. The institutions began using methods to polish and build the aptitude around cognitive skills like problem-solving, logical reasoning, and management. 

Their application and curriculum are emphasizing on these abilities as these abilities are an integral part to stand out among the competition. Their syllabus is built in a way that focuses on facts and theoretical knowledge but also incorporates real-life scenarios that can prove helpful in professional life. 

Now students are being encouraged to focus on other skills as well. Like, leadership skills, team-building skills, communication skills. Some real-life scenarios are applied in the classroom to prepare the students to deal with real-time problems. These methods are imbued in students via offline and online classes. 

This is a much-needed change in the education sector. This not only helps the students gain theoretical knowledge and develop their skills. But also enable them to navigate around the professional world. This gives them a needed confidence boost and turns them into capable and desirable candidates who are preferred by the companies. 

3. Emphasis on Innovation 

Attention to detail and innovation is vital in today’s world. Innovation has become essential in every sector. From linguists to artificial intelligence, the sheer amount of choices available today enables the candidates to pursue their dream. 

Now they can get professionally trained in their preferred sector and gain the skills and knowledge to make a career in their field. The vast amount of choices available is one of the largest trends we see in 2021. 

Memorizing was a thing of the past. Now the students learn by doing. The assessment module and course structure are designed in a way to help the student slean practically. They are made to understand the merits of a study. 

The candidates are now encouraged to choose what they are interested in, mainstream subjects and studies are not forced upon the candidates. The obsession with engineering, medicine, or even law is diminishing, and new opportunities are suggested to help the candidates choose a path that excites them. 

Newer fields and specializations have made a way for aspiring candidates, and the scope in these fields is enormous. 

4. Personalization of learning space

This trend is the most welcoming, and it’s about time that we understand the phrase “every kid is unique”, and so are their learning patterns. Formerly, the personalized learning methods were only seen in specialized schools and institutions. But now more and more learning institutions are opting for this trend and helping the specially-abled students learn alongside normal students.

To overcome the bias against specially-abled students, this is an important step. This trend will allow these students to learn in a similar environment as other students and open up the world of possibilities for them. 

These students can now enroll in prestigious institutions for higher studies and reach out and achieve either dream. Who knows, maybe we will see more geniuses like Stephen Hawking. This inclusion can be the largest trend of 2021.

5. Open Learning Platforms

One of the latest trends of 2021, is the rise in open learning platforms like Open Colleges. These open spaces help make the learning methods more convenient for students. The students can access all the course materials in one place, submit their assignments online and even check their grades. 

This space is easy to use and makes it convenient for students to learn and access information. And in times like these, where we are in the middle of a pandemic. This trend is a welcoming one and much-needed.

6. Rise in Automated Schools

With the rise in technology, schools rely on online assessment systems, to make it convenient for students and even parents to access the assignments online. In addition to the online assessment system. 

Automated attendance is also a rising trend among schools. Schools use facial recognition to ensure attendance and even use automation for other administrative tasks. When the students interact with online technologies, their digital footprint can be traced and used to make learning modules. The teachers and instructors can focus on the learning.  

7. Adaptive Learning

Personalized learning programs can help the student learn at their own pace, and the teacher can tailor the information as per the students’ requirements. With personalized and adaptive learning, teachers can create learning experiences that are engaging and personalized. This is a meaningful approach to education, and all the students get the necessary attention and can perform better in academics. 

Conclusion 

The educational trends in 2021, lean towards technological transformation and the introduction of digital channels in classrooms and teaching methods. The education sector has a lot of potential. This sector offers a lot to a diverse audience. The changes in this sector directly reflect on the other sectors. 

Creating capable candidates who can bring change to the world is the responsibility of the education sector. The more opportunities provided in the education sector will broaden the field in the rest of the world. Trends like personalized learning, and enabling students to learn openly are some of the long-overdue changes. These will result in benefits in upcoming years. 

The availability of upskilling courses for all professions will help the candidates learn and polish their skills. And become a capable candidate that will be preferred by the companies. Many portals offer professional courses for aspiring candidates. 

They can enroll and learn at their convenience. There is no end to learning. We keep learning and evolving. Even though we are not actually in education, we can still learn. These trends do not just affect the education sector but all of us. Let’s welcome them and hope for even better trends in upcoming years.

The Cloud: How does it Work? Explanation in Detail

We have been talking a lot about the Cloud in recent years. It is a new way to store and manage data and to dematerialize it. The most relevant examples that we can give of Cloud use are the countless online tools that we use every day and in which we store documents accessible via any computer or smartphone. Everything can be kept online, and this is possible thanks to the cloud and the advanced technology behind it.

What is Cloud Computing?

Your documents, applications, and other types of data, you can store on the hard drive of your computer or rather choose the Cloud. In the second case, it means that you are using storage computer resources accessible from the web.

Cloud reflects the fact that we often have the impression of placing our data in an intangible environment (different from the computer that we can touch) to find it there at any of our selected times, just by connecting through the internet.

If you’re using Gmail, Yahoo, or another similar webmail, you’re already using the cloud. And you may notice that your old emails and drafts are still available and right where they are, no matter what device you connect with. Google Drive and Dropbox are also cloud services capable of storing a very large amount of data that would be impossible to keep if you had to use your computer.

The tools in the Cloud are in fact very numerous and they all work on the same principle: the use of several shared and remote servers to store data and make them accessible to the Internet. 

It has been a long time since the Cloud has been used by IT specialists or companies, but its use is becoming more general and has ensued an increasingly publicized craze. What everyone knows and uses tends to be talked about more. The Cloud is also becoming an economic reality because Internet users sometimes have to pay to subscribe to the Cloud service of their choice, although some may be totally or partially free.

The different cloud systems

There are different offers available to access the Cloud, that is to say, different ways to use the storage capacity that the principle allows:

  • The SaaS: Also referred to as Software as a Service, which enables users and businesses to be able to access an application or software via a monthly or annual. This is the simplest method, but also the most used. It does not require any installation, but the accesses are done naturally by using an internet browser. You will then be able to fully use your new software for the duration of your subscription;
  • The PaaS or Platform as a Service: This method allows you to have a computing environment that can help you manage the installation, configuration, and even the use of your applications. Here, you will be able to perform updates for example, unlike SaaS where you only have options for use and not maintenance. All this goes through web hosting which helps the platform to operate and the hosting of various applications;
  • The IaaS or Infrastructure as a Service: Here, it is also subscribed to have a complete IT infrastructure, including servers, network, backup, and storage systems available in the provider’s data center. Thus, you have a Cloud service as if you had all the computer equipment necessary to use your own data center. No usage restrictions on your consumption since this virtual material belongs to you as long as you keep your subscription up to date.

Some structures or companies still prefer to have their IT system in-house for questions of confidentiality and data security, while others are quite confident about all (or part) dematerialization in the Cloud.

What is the use of the Cloud?

The primary utility of the Cloud is its flexibility and accessibility. You can access your data, applications, or servers from any workstation connected to the Internet, regardless of the screen size, the operating system, or the brand. The synchronization options reinforce this accessibility, to switch the grip from one device to another without the need to disconnect or move.

This saves a lot of time, an almost unlimited space, a power-sharing solution, but also money, when we consider how much all the equipment required for the storage of a large volume of documents or virtual machines would have cost.

And yet, we all know that current work and communication habits adapt very well to the use of the cloud, to a certain extent. This is also why USB keys are used a lot because it is often necessary to transfer data from one computer to another or to a smartphone, or to a tablet. It is thus possible while being at the office, to record any information in a SaaS software in the form of video, audio, or written document (Facebook, Gmail, Twitter, Spotify, or another software), to consult it later. in transport or at home.

It’s more or less affordable and adaptable costs, depending on the number of users, for example, make cloud services an option increasingly considered as an alternative to traditional and physical means of storage.

Cloud and online applications

We use the cloud almost every day by using online applications. They are very easy to use and exist in different fields. We have seen the example of Gmail and Yahoo, to name but a few, which are online applications or software on which most of us have opened one or more free accounts.

These applications are now democratized and there is little doubt that they are part of what made the current success of the Cloud.

There are several specificities that distinguish them: online applications adapt to all operating systems; they do not need to be installed on our computers, but just need a sufficient internet connection to function; they help with group and online work; they have a relative level of security (a big drawback).

We have the example of Google Drive for data storage, WeTransfer for sending very large documents, or Canva for photo editing.

Advantages and disadvantages of the cloud

If Cloud services are in demand as much by individuals as by companies, it is because the advantages they contain are interesting, to say the least. On the other hand, there are reservations with regard to this dematerialization model which does not allow the same control as that which is possible with hardware.

Among the advantages of using the cloud are:

  • A reduction in cost, especially for structures that no longer need to acquire all the computer equipment that was once essential to start their activities. The initial investment costs are reduced, especially for startups;
  • The possibility of unlimited bandwidth and storage ;
  • Access to very high-quality services without paying prohibitive costs;
  • The possibility of strengthening data security.

The downsides of cloud storage are nonetheless worth considering:

  • The Internet is the engine of the Cloud, if a failure occurred, the entire activity of the structure would be disrupted;
  • The structure remains technically dependent on its Cloud service provider;
  • The computer system is no longer under the perfect control of the structure and the applications used may change at any time, in favour of other more efficient or more adapted to the service provider’s equipment;
  • Confidentiality can no longer be guaranteed 100% if we consider possible cyber-attacks or technical failures;
  • Questions also arise from a legal point of view as to the location of the data and their subject to the laws and regulations in force in the national territory where the servers are located (e.g. data placed in Amazon or Google Drive, with servers based in the United States are thus subject to the “Patriot act” with the possibility for the American government to consult this data at any time).

Is the cloud secure enough?

The convenience of the cloud is no longer in doubt, but what about security?

Even though online applications can be considered reliable, until proven guilty, hacks are a common occurrence, resulting in massive theft of data for obscure purposes.

It is therefore up to a cloud service provider to ensure that the security of its users’ data is reinforced so that hacker attacks always end in failure. However, we must admit that we cannot completely trust the online applications (Dropbox, Google Drive, Skydrive, etc.) that we use and in particular to keep our files safe.

What the experts recommend is to at least try to have strong authentication, which will not allow a hacker to enter an email or an online storage platform. Today, for example, there is what is known as 2-factor authentication (2FA) including the password and phone number. The simple fact of using a very strong password, difficult to guess with numbers and symbols, is undoubtedly already a useful precaution.

You should also not take the risk of placing some row data. We will take the example of bank identifiers or medical data; these are not things to be communicated remotely and on any platform.

Online applications, in themselves, are not always honest with users since they have confidentiality rules approved that stipulate the use of user data in order to improve their services, without falling into the details. You can therefore take care to read the conditions of use that we present to you or at least make a restriction on the type of documents that you share.

You always have the option of turning to online applications that you trust more because in the end, the cloud has become essential, if only for basic use.

Some Cloud solutions, especially recommended for companies, also allow the use of an encryption key for your accesses so that only you can consult your data.

The leading providers of free cloud storage

In general, online users are often looking for cloud services for free storage. These online applications are free, but with paid options when a certain level of storage is exceeded.

Some of these online storage tools include:

    • Google Drive: the Google tool that you can access for free as soon as you have a Gmail account;
    • Dropbox;
    • Microsoft OneDrive;
    • Apple iCloud;
    • Amazon Cloud Drive;
    • OpenDrive etc.

The cloud market is currently very developed and several tech giants have also taken to it by creating their own cloud service, with increased demand from users. Companies are also increasingly using the Cloud, taking advantage of low-cost plans and thus saving on their expenditure on IT resources. The Cloud is also very practical to facilitate the use of digital tools even if it sometimes arouses a certain suspicion. However, we have to believe that this computer system is well on its way to last and to develop further for years to come.

Signal App: Everything You Need To Know About The Messaging App

Ever since Whatsapp updated its privacy terms. People started looking for new ways to stay connected with their friends and family members. Numerous apps came into the limelight, but the one that stole all the thunder was the Signal App. Thanks to Elon Musk’s tweet, people are downloading the app at god’s speed. Whenever there is a new trend, people are often baffled and look to gain information about it. If you are one of them, then this article can help you gain some insights about the app. In today’s article, we will decode all information there is to know about this app. 

What is Signal App?

The signal app messaging and voice-talk platform, which is free of cost, similar to WhatsApp. The most important difference is in “Privacy”. Even, the tagline of the Signal messaging app is “Say hello to privacy”. A line that most users will resonate with, given the current circumstances with Whatsapp.

If you visit the Wikipedia page of the signal app, you will find that it was launched on the 29th of July 2014. But according to the current information, the stable version of the app was released in December 2020 for android and in January for the IOS platform. 

The Signal app runs on donations it gets from the non-profit Signal Foundation organization. Brian Acton, the co-founder of WhatsApp, and Moxie Marlinspike, the CEO of the Signal messenger app. started The Signal Foundation.

How Does Signal App Work?

All things considered, using the Signal app is quite simple. You can easily download it onto your iPhone, Android, or desktop for free and begin chatting with your friends and family members. Registration is done with simply your phone number, and the app would then be able to scan over your contacts to see which numbers in your contacts are using Signal messaging app. 

You can use this app on either your phone or PC. If you start a chat using your phone, you can use a QR code to sign in on your PC and continue the rest of the conversation there — however, you won’t have the option to see the past messages (the ones you sent using your phone). Signal messages are stored on mobile phones, rather than in the digital space of the app. That is because Signal uses an open-source protocol to encrypt everything from messages to recordings, voice updates to photographs. In tech-talk, that implies you can look at the source code keeping your Signal messages hidden for just yourself on GitHub. In easy words, it implies that your messages will remain your messages — if you are the only one who can access your phones, then you’ll be the only one who’ll see them.

Key Features of Signal App:

Messaging

It’s a messaging app. This app lets users send messages between two phones. Like you can send instant messages to your friends and family members online. In this way, you don’t need to pay SMS charges to your service provider. 

Private and Safe Data Sharing

It provides a messaging network that lets the user send messages with end-to-end encryption which keeps your messages secure. They don’t invade your privacy by reading your messages and listening to your calls. The platform is secure so no one else can read or listen to your private conversations

Voice and Video calling

You can now call and video call anybody in this world with no network charges by the assistance of the internet. The signal messaging app gives perfectly clear voice and video calling services to users. 

Sticker 

You can send stickers to your contacts with encryption. Along these lines, nobody can decode your sticker. You can also make and offer your custom stickers. 

Group

It has a group feature which lets you create a group with your family, friends and other contacts. Thus, you can undoubtedly share information with every single individual from the group. 

No promotions and no trackers 

The signal is a totally non-profitable app so there are no advertisements on this app. No advertisements imply no affiliate marketers and no trackers exist to follow your activities. 

Open-source 

It is a totally open source project for engineers. Thus, anybody can assist with building up this app for making it more user-friendly and more secure.

Benefits of Signal App:

  • The messages, audio calls, video calls, group calls and even the stickers sent are start to end-to-end encrypted. This encryption technology that Signal originally created is presently used by WhatsApp and Skype. 
  • The messages on your chats can be set to disappear after a specific time. This time frame can be decided by the user based on their needs. 
  • The users cannot add members to their groups without their permission.
  • The messages on Signal are stored on the gadget itself, which is your cell phone. The Signal app staff don’t store the information nor does it permit the users to backup their Signal conversations on the cloud (Google Drive or iCloud). This implies that when you transfer to another number or get another cell phone, you can’t move your messages on the new gadget or number. 
  • The signal app can also work on the PC or desktop simply like WhatsApp. However, the difference here is that all the chats that are on your cell phone don’t get stored on the PC and the other way around. 
  • You can send a message to any contact that exists on your contact list. Customers who don’t have the Signal messaging app installed on the phone will be sent messages through normal SMS. 
  • The sound and video calls on the Signal app are end-to-end encrypted. This can be seen through the little padlock symbol close to the telephone symbol. 
  • To move a current WhatsApp group to the Signal app, you need to make another group on Signal by adding only one individual from the group. Afterwards, share a generated group invite link on the WhatsApp group that you need to move to the Signal app. The users on WhatsApp can join the recently formed group on Signal by tapping on the link. 
  • You can also send messages to yourself on the Signal app through the ‘Note to Self’ choice. By this, you can keep a rundown or a note of significant things. 
  • The signal app gives you an alternative to blur your profile photograph.

WhatsApp vs Signal vs Telegram

WhatsApp is right now the biggest messaging platform on the earth, with more than 2 billion users. Telegram has around 400 million users, while Signal has around 20 million users. 

While WhatsApp stands undefeated given a large number of users, we can’t avoid the developing market and popularity of Telegram and Signal. 

The update in WhatsApp’s privacy policy has given a chance for the market for these two other giants to grow.

WhatsApp 

WhatsApp has all the ingredients for a perfect recipe. This social messaging app has also added a payment feature to its hat. Users can add up to 256 members in the group. You can broadcast messages to various contacts, and also support voice and video calls, both for people and groups. 

    • Group video calls (that can handle 8 users at any given time).
    • WhatsApp Status feature (also known as WhatsApp stories).
    • Whatsapp allows you to share a wide range of files and documents (up to 100MB).
    • Photographs, videos and audio notes can be shared up to 16 MB.
    • Users can also share live location with their contacts. 
    • WhatsApp backup and restore messages and data on google drive and iCloud.
    • WhatsApp uses end-to-end encryption (E2E) for messages, video calls, voice calls, photographs and any other data. 
    • WhatsApp utilizes E2E protocol created by Open Whisper Systems, same as Signal

Telegram 

Telegram offers support to groups with up to 200,000 contacts. Known for its huge and monstrous groups, Telegram offers a lot of group features, for example, bots, surveys, tests and hashtags, extensive for a large group experience. 

    • Telegram offers self-destructing messages. These messages disappear after a said point in time. 
    • You can share files as large as 1.5 GB on Telegram. 
    • Telegram supports video and voice calls as well. 
    • Telegram supports E2E a secret chat feature.
    • Telegram has confirmed that it shares 0 bytes of data with any third party or government.

Signal 

Going to the most latest member to the messaging party, Signal offers secure messaging, voice, and video calls and these are end-to-end encrypted. You can make groups, but you can’t broadcast messages to numerous contacts at once. Signal also lets its users make group calls. 

    • Like Telegram, Signal also supports self-destructing messages 
    • A Note to Self feature is also a highlight of the app. You can share your thoughts and ideas under this feature.
    • Signal permits relay voice calls to its users, identity isn’t shared, same as using a VPN 
    • Signal uses back-end user-facing encryption administration 
    • It uses the open-source Signal Protocol to accomplish end-to-end encryption 
    • Signal additionally encrypts your metadata offering several layers of security

WhatsApp vs Signal vs Telegram: Which Messaging Giant is More Secure?

WhatsApp doesn’t encrypt backups (cloud or local). Whatsapp also doesn’t encrypt metadata, not at all like Signal, which is used to convey conversations between two endpoints. WhatsApp group chats have been before discovered to be filed on Google search, significant information breach. 

Telegram group chats are not encrypted except if you use Secret Chats, which again just lets you chat to one contact at a time. 

Regarding client security, Signal offers the most secure communication you can find on the internet. But the most secure app Signal falls short when it comes to all the fancy features WhatsApp and Telegram are offering. Signal naturally encrypts all the local files with a 4-digit passphrase. It also encrypts all the group calls.

What Sets Signal App Apart

FACEBOOK  DOESN’T OWN SIGNAL

It has been shown to us time and time again that we cannot trust Facebook with our personal data. However, well over a billion people decide to send their most personal messages over apps made by the organization. And keeping in mind that Facebook says it can’t access messages sent over WhatsApp and doesn’t access messages sent via Facebook Messenger. But the organization mines your use of those apps for other information, for example how frequently you chat with somebody and whose contact numbers you have saved in your contact list. 

Facebook doesn’t permit outside protection and security specialists to assess its data collection methods, nor the code of its messaging apps. That implies we simply need to take their word for it and trust that they are not taking advantage of any personal information. Also, many studies have shown that not a lot of people are willing to trust the organization with their data.

SIGNAL DOES NOT MINE USERS DATA FOR AD TARGETTING

So why escape from Facebook Messenger and WhatsApp to Signal and not some other messaging app? Since Signal is the only major messaging platform that can run on various platforms (such as android and ios) and avoids following you and your connections to other people. All the other major apps out there track you. And while Apple messages don’t. They are only available to iOS and macOS. Android users are not that lucky, so Signal app might come in handy.

About Signal App Security And Privacy

With regards to security, the Signal messaging protocol is by and large viewed as the most secure messaging protocol available. It is acceptable to such an extent that numerous other messaging apps, including Facebook Messenger, Skype, and WhatsApp, have claimed to adopt the protocol to be used in their apps. 

With regards to privacy, Signal is a sure shot winner. As we examined before, Signal just records three pieces of data about their users. This is far less data than other platforms collect. Furthermore, Signal gives you a chance to take the privacy protections a step further. There are a lot of articles that can give you detailed directions on how to create your Signal account without using your phone number.

Make your iPhone App more secure with SSL Pinning

What is SSL pinning?

An HTTPS connection has a valid certificate and a cipher suite. The certificate is presented to server presents during handshaking. It is the essential component that serves as proof of the identity of the server. The client will trust the server if it provides a valid certificate signed by one of the trusted Certificate Authorities. Otherwise, aborts the connection.

An attacker can either install a malicious root CA certificate to user devices. So, the client will trust all certificates signed by the attacker, or even worse, compromised a CA completely. Therefore, trusting on the certificates received from servers alone cannot guarantee the authenticity of the server. Your server is vulnerable to a potential man-in-the-middle attack.Secure Socket Layer Pinning is a technique used in the client-side to avoid a man-in-the-middle attack. This technique validates the server certificates even after SSL handshaking and pins a list of trustful certificates to the client during development. They, then use them to compare against the server certificates during runtime. The connection disrupts if there is a mismatch between the server and the local copy of certificates. This ensures that no further user data goes to that server. In short, SSL pinning ensures the user devices are communicating only to the dedicated trustful servers.

Developers must take extra caution in SSL Pinning. When a pinned certificate expires, the server gets a new certificate. The new certificate is different from the pinned certificate. So, the clients will not trust the updated certificate and therefore terminate the connection. Communication established between clients and servers is basically ‘bricked’. Therefore, to avoid such a situation,  always pin the future certificates in the client applications before release.

There are two ways to achieve SSL Pinning in client applications.  You can either pin the whole certificate or its hashed public key. The hashed public key pinning is the preferred approach that uses the same private key for signing the updated certificate. This approach can save the trouble of pinning a new hashed public key for a new certificate, and reduce the risk of app ‘bricking’.

How to make your iOS Apps more secure using SSL pinning?

SSL pinning comes into the picture as one of the best app security options while looking for ios game application development services. A system library does the task of maintaining the SSL session. The app trying to establish connection does not determine which certificate to trust and which not to.The SSL encryption happens based on Public Key Infrastructure and a session key. Encrypting and decrypting public uses a lot of energy and slows down the communication process. That is when the session key came into play. Asymmetric session key exchanged with the SSL handshake reduces the risk of asymmetrically encrypting data at the source and decrypting it at the destination.The certificate’s chain of trust determines the security aspect of SSL. The client checks the server’s SSL certificate as the communication process starts. The client will check if the received certificate is an issue by the Trusted Root CA store or other user-trusted certificates.

Although SSL is pretty much unbreakable, there is still an actual threat of the man-in-the-middle attack. This can happen with ARP poisoning and DNS spoofing. With ARP cache poisoning, an attack is possible depending on the Address Resolution Protocol. Address Resolution is responsible for mapping the IP address to the devices MAC address. For example, consider a network containing a common user’s device A, the attacker’s device B and router C.Device B sends the ARP reply packet to the device A acting as router C. Then, A sends another ARP reply to C identifying as device B and completes the attack.DNS spoofing is an attack technique that corrupts the name server’s domain name mapping. Here, the attacker forces the DNS to return an incorrect IP address and divert the traffic to theirs.

There are different ways through which you can implement SSL Pinning in iPhone game development services. You can secure your iOS with SSL pinning using NSURLSession, AlamoFire and AFNetworking. NSURLSession SSL pinning is a bit tricky. Here, there is no option to cancel all responses that do not match with the certificate automatically. To implement SSL pinning on NSURLSession, we need to do perform all checks manually.

Alamofire SSL pinning is simple. The ServeTrustPolicy.certificates Bundle method in AlamoFire returns all certificates in the bundle. First, we load the certificates in the created ServerTrustPolicy object. Then the object is instantiated with a dictionary to map the domain name to the ServerTrustPolicy. We are only pinning the predefined domain in AlamoFire.

SSL pinning in AFNetworking is straightforward. You have to assign an AFSecurityPolicy policy object to the AFHTTPRequestOperationManager. It will scan through your bundle by default.

Automation Testing Interview Questions

Are you a software geek preparing for an interview? Well, we wish you a hearty, ‘All the best!’ 

Nervous? About What? Automation testing! Here are some questions you need to prepare to ace an interview!  

Test automation has an essential role to play in the entire software development lifecycle.  

A lot of times when people prepare for an automation testing interview, they focus only on the automation tool-specific questions.

However, people should also consider the fact that learning and knowing about the automation tools is not the same as knowing about the automation testing and hence it’s not the ultimate goal. 

 Thus, whenever you are preparing for a ‘test automation’ interview, it is essential for you to consider ‘Automation’ as a whole and focus on its framework and all the steps involved. 

 

What are automation and automation testing? 

 Automation is any form of action that can help reduce human effort. 

Automation testing is of course, automated. This is completely different from manual testing as in manual testing, a human is responsible for testing the functionality of the software in the way a user would. 

Automation testing is a software testing method used to test and compare the expected outcomes with the actual outcomes. It is achieved by using automation tools or by writing test scripts. 

Automation testing is used to automate testing tasks that are difficult to perform manually like repetitive tasks. It requires far less time than manual testing due to the fact that automation testing is done with the help of an automation tool while humans perform manual testing. Less time is needed in exploratory tests and more time is needed in maintaining test scripts while increasing overall test coverage just like mystery rooms.

 

What are the tests that can be automated? 

Following are the things/tests that can be automated: 

  • Build deployment 
  • Test data creation 
  • Regression test suite 
  • Smoke / Sanity test suite 

Automating behind the graphical user interface like testing of APIs. 

 

Is test automation useful or not? 

Automation testing proves to be useful in the following scenarios: 

Non-functional Testing: Automation-testing is used to test the non-functional aspects of an application. 

For Example, Performance testing and load testing are very difficult tasks for humans to track and analyze. 

Regression Testing: Regression testing is done in case of a bug fix or new module implementation, then is important to make sure that the already implemented and unchanged functionality is not affected in any manner. In this case, the people end up running the regression test multiple times. 

For Example: After each change request or bug fix and after every iteration in the case of the incremental development approach. 

Repeated execution of the same tests: Sometimes, it is important to run the same set of test cases for a different set of data. Also, after each build release or on multiple hardware and software or a combination of hardware and software. 

Automating the test cases in the above scenarios helps in maximising the speed of testing and minimising human errors. 

Complex calculation: Automation testing in this case helps in checking or testing scenarios that are prone to human errors. 

 

 Is it possible to achieve 100% automation? 

100% automation is difficult to achieve because then there will be a lot of edge test cases and some cases that are not executed very often. Automating these test cases which are not executed very often will not be able to add value to the automated suite. 

 

How can we identify the test cases which are suitable for automation? 

The most important step towards automation testing is the identification of the most appropriate test cases for automation. 

 

How to decide the automation tool that one should use for their Automation testing in the projects? 

To identify the best tool for Automation testing for your project you need to do the following: 

  1. You need to understand your project requirements thoroughly and identify the testing scenarios that you want to automate. 
  2. Lookup and search for the list of tools that support your project’s requirements. 
  3. Plan out your budget for the automation tool. Then, choose the tools within your budget. 
  4. Be sure that you already have skilled resources for using the automation tools. If you don’t have the necessary skilled resources for using the automation tool then identify the cost for training the existing resources or hiring new resources for the work. 
  5. Compare each automation tool with the key criteria: 
  6. Once you have compared the best automation tools for your purpose, select the tool which is within your budget and supports your project requirement, and gives you more advantage based on the key criteria. 

 

What are the key criteria for automation testing tools? 

 

The key criterion for automation testing tools is as follows: 

Does the automation tool have test reporting functionality? If not, can it be easily configured to the tool? Is that automation tool suitable for cross-browser support for web-based applications? How many different testing types can the tool support? 

  • How many languages does this automation tool support? 
  • Is it easy to develop and maintain the scripts for the tool? 
  • Can a non-technical person also execute the test cases with some simple training? 

Is the tool able to support different types of platforms like web, mobile, desktop, and much more based on your project requirements? 

 

What is the next step after deciding the automation tool to use? 

Once the tool is finalised, the next step is to design the framework. 

What is the framework? 

A framework is a part of the structure of the entire automation suite. It is also a guideline, which when followed properly, can result in a structure that is easily maintained and enhanced. 

The guideline of the framework includes: 

  • Handling of environment files and properties file 
  • Reporting of data 
  • Handling logs 
  • Coding standards 
  • Handling the test data 
  • Maintaining and handling the elements (object repository in QTP) 

 

Final Words: 

The questions above are the main questions that are important for automation tools or programming language. Automation testing interviews also include tool and programming language-specific questions depending upon the tool that the people have worked with. 

Most of the test automation interview questions are centered on the framework that the person develops, so it is recommended that everyone creates and understands their test framework thoroughly. 

Have you gone through all the Q&A? Now, get ready and crack any software interview!

Conventional Capabilities Online at SharePoint

This year, Microsoft released several new SharePoint capabilities to help boost user engagement with the platform. In particular, Microsoft continued modernizing SharePoint Online, adding new features. Furthermore, it plans on improving the user productivity of the platform when employees use it for accessing and interacting with their digital assets. 

SharePoint Online is offered as a communications and collaboration tool for intranets. As the platform is being updated by Microsoft, SharePoint development services also feel the need to improve to stay on the competitive edge. 

SharePoint Online Capabilities

A SharePoint development company today provides updated services as Microsoft continues to upgrade the platform to provide better solutions to organizations across all industry verticals. Typically, the flexible platform includes several conventional capabilities, such as the following.

  1. Intranets

SharePoint Online lets you set up an intranet for the sharing of business information. It acts as a meeting room for each person within the company to visit during their working session. Employees could find the latest organization news, announcements, or scheduled tasks. 

Moreover, it could even opt to customize dashboards by the department. SharePoint has tools for setting up platforms for enhanced employee interactions. 

  1. Extranets

Setting a website in which you could interact with business partners and other stakeholders is also possible with SharePoint Online. This is perfect for the exclusive sharing of common interests with partner organizations. Moreover, you could also provide or access to affiliate services. 

  1. The Document Management Systems

You could exactly use it in the same way as a traditional file server, complete with security groups and folder structure to determine who has access to what. Some differences however are:

now you have any device, anywhere, secure files access

sharing externally is possible with controls

nothing to change

With SharePoint Online, users are at the top to build a site that could have several libraries or sub-sites even. Big organizations could enable every department to have its sub-site for boosting communication. SharePoint takes into account that each organization has a unique classification in terms of storage, and offers flexibility for customizing web structure according to complex business needs.

  1. Collaboration

The platform servers as a collaboration tool for various people working on the same project and sharing the same documents. Everyone will have a version of the same documents, making it easy for all to stay updated with the project. The platform also acts as a portal to connect companies in different locations. 

Rather than having to wait to share and interact ideas during a meeting, people could reach out to one another anytime, fostering innovation and boosting productivity. 

  1. Business Intelligence Capability

With SharePoint Online, you can have a birds-eye view of company operations. This provides several ways of making well-informed decisions. Searching through files and find bigger patterns to show progress or setbacks experience is easy. 

SharePoint Online is also great in discovering trends and relationships between various variables, such as the way a marketing team does interaction with the sales teams to drive sales and leads. Data could be used to get different departments on board. 

  1. Security

With extensive security features, SharePoint Online enables you to configure security at a document, folder, site, or library level. This way, information is not visible to the view of the user if they have no required access level. 

You could also opt to control the document life cycles with compliance policies. For example, you could use policies like archival, routing, or expiration policies. 

Why Organizations Migrate to SharePoint Online

To keep up with the improvements made by Microsoft on the SharePoint platform, a SharePoint developer has to build solutions that meet the evolving needs of customers. These days, more and more organizations are migrating from On-Premise SharePoint to Online SharePoint. Here’s why. 

 Automatic Updates

You must factor in the costs expected that come with an upgrade with SharePoint On-prem. Online SharePoint however provides automatic upgrades to the latest versions as well as additions. You don’t have to worry about patches, or update maintenance, enabling you to focus on the business aspects of things. 

Easier Management

SharePoint On-Prem works using a database server, web front end, and the app server to deliver the services configured on them, making management quite complex. You need to hire an IT team or a SharePoint consultant team for maintaining the server, do patches and updates. SharePoint Online on the other hand has nothing to manage, meaning that you could eradicate the need to purchase more hardware, like servers. 

Migrating of Content

With SharePoint Online, you could only move content once. With the on-premise, it sets a time limit, which ranges from three to five years for the upgrades required. Online SharePoint in contrast does not set a limit for the time you get to remain until moving to the next version. Thus, when you move content, you only have to do it once. 

SharePoint Online 2020, the New Features

  1. Microsoft Intelligent Search Integration

Microsoft, with OneDrive and SharePoint, plans on releasing an AI content search engine named the Project Context in acknowledging that often employees struggle to locate pertinent data in presentations and emails. The new service has AI algorithms designed for Office 365 content interaction to deliver search results going further traditional keyword-based searches. The AI engine could be used for sifting through all data accessible within the ecosystem of Office 365, asking queries with natural language. 

  1. Enhanced UI Navigation for SharePoint Users

Another new feature is the responsive mega menus, which display and render on mobiles or a full desktop version for all SharePoint websites, which include those not related to hub websites. The management feature is attractive to developers since it provides a way of delivering shortcuts natively to the various SharePoint web pages, with one navigation menu that could list them under various headings. 

  1. Facelift for Yammer

Yammers, an enterprise social networking platform lets users with a similar email domain connect received the much-needed facelift this year. In conjunction with SharePoint, the platform displays user conversation feeds through a web part in the web pages.  

Today, Yammer provides enhanced and new features to users, like customizable Yammer, feeds, giving users the ability of filtering content into what they want to see. 

To Conclude

For you to make the most of SharePoint Online, you have to work with someone who truly knows how things should be done, like a SharePoint consultant Sydney for instance.

The Stages Of An Online Purchase And How To Improve The Customer Experience

The shopping experience is one of the most important factors to take into account when we study and delve into an online purchasing process.

A purchase process is all those phases that the consumer or customer of a product goes through from the moment they have a need until they are happy to purchase a product or service that meets their needs to the utmost satisfaction.

In this article, we will take a walk through the different stages of an online purchase and we will see what added value you can give the consumer to optimize them.

1. The importance of the shopping experience

A pleasant, safe, and comfortable online shopping experience is the key to encouraging the customer to buy again in your store. It is increasingly difficult to differentiate yourself from your competitors and an original and effective way to do it is by focusing on the service you are giving to your client. Every day it is more personalized and they look for different ways to surprise the public.

2. Stages of the online purchase decision process

The stages of the online purchasing process that a customer takes into account from the moment a need arises until it is covered are the following:

  • Realize that you need it.
  • Do your research to find out how to meet that need.
  • Decide which option to choose from those found.
  • Buy the chosen option.

3. Phases that will improve the online shopping experience for your customer

The online shopping phases that we have to take into account so that the shopping experience is ideal are:

3.1) An attractive home page

The home page of your online store is the first impression that a user has of your brand and of what you sell. Try to give a good image with the help of large and attractive banners, always in accordance with the style or design of your online store.

In them, you can offer the products you have in a promotion or show a special category. Adapt your home page according to the season of the year or if it is a special day such as Valentine’s, Christmas or summer.

The personalization to your customer is a key element to improve the online shopping experience. Every time you can know more about the client through a good client management tool (CRM) and social networks. This allows you to know their tastes, what they are looking for in your store and what environment interests them.

It allows you to adapt your experience Marketing strategy to your client in a personalized way. So if you see that your client publishes photographs of mountain excursions on social networks, offer him a product related to nature that may be useful to him.

Don’t forget to congratulate him on his birthday or anniversary with the company and offer him a discount as a gift. You can present these actions on your home page or create an emailing campaign.

If you don’t have a customer service phone number, you should have the option to send a message to answer questions. Even if you are quick to answer emails, the client does not know when he will receive a response from you and that creates a feeling of unease and impatience. The client always looks for an immediate answer .

So I recommend offering personalized treatment through the integration of a chat in your online store to create a more enjoyable and effective online shopping experience. In this way, you will be able to answer their questions in real-time and show that you are always available to the customer.

3.2) A professional product sheet

I imagine that you have been told a thousand times how to present a product sheet: use large images with a white background and high quality, make known all the characteristics of your product, use cross-selling or up-selling techniques, etc.

An added value that you can bring to your product file is the testimony of the online shopping experience of other consumers.

The stars as a method of evaluation of your product is already quite seen, although it is still as effective as at the beginning. Let users leave comments and opinions about your product .

Marketing is a thousand times more effective than you can do. It is also very important to add buttons for social networks, for example, to “like” your store on Instagram or to tweet the product.

This content will be published in the stories and profiles of the users, it will be visible to the entire network of friends. They will be sharing the online shopping experience with their friends. Again, a friend’s opinion is worth a thousand times more than yours.

3.3) A secure payment

More and more people are daring to buy online, although there are still people who do not take this step by giving information about their bank account or credit card. Use trusted and secure payment stamps to create a reliable online shopping experience.

Add these stamp icons to checkout pages to inspire confidence in your customers. These are some of the stamps that you can integrate:

The more forms of payment you offer, the more options the customer has to have an online shopping experience adapted to their preferences. The different forms of payment that you can present in your store are: bank transfer, credit card, Paypal or cash on delivery.

Although the latter is a bit risky because the customer can return the product without paying the shipping. 

It is also important to add a section on secure payment and payment methods in the “General conditions” of your online store. In this way, the client always has access to this type of information and you inspire tranquility to the user.

3.4) A pleasant shipment

The shipping phase is the one that will unquestionably decide whether it has been a successful or disastrous online shopping experience. The desire to have the product at home quickly is very high which may not always be fulfilled.

So I propose to focus on other aspects that you can really control and improve to impress your client. The presentation of the package that the customer receives is the first direct contact that the consumer has with your product.

Take advantage of packaging techniques to excite your customer. Invest in a tissue paper that wraps the product in a funny way and in a nice box with a bow, it will be a little more expensive, but it is very nice to receive a package of these characteristics, so they will probably repeat the shopping experience online in your online store.

Many times problems arise in this phase of the purchase and most of the time it does not depend on you. Whatever happens, don’t forget to communicate with your client and inform them. If the package is late, send them an apology message and let them know how late it will be.

If the package or product arrives in bad condition, send him another one (don’t wait for him to return it) and add a gift for the inconvenience. It is inevitable that these things will happen, but you can fix them and surprise your client even more.

3.5) A simple return

A return doesn’t have to be a bad thing. Sometimes it is not the size we need and we have to return the product. To end good online shopping experience, clearly define the steps to take to return a product.

Don’t use complicated words and add a link to create the shipping label. Although if you prefer, you can send the label inside the package so that he only has to fill it out and send it.

If you can afford it, I advise you to return shipping free. It is a way of worrying about the customer getting the ideal product. Although you also have the option to offer free shipping only when the products are defective and not when it is a size problem.

Always remember to write everything down in the “Return Policies”. Many times it is a hassle to wait at home for the courier to come to take the package. In this case, the customer can go to the collection points and Click & Collect that allow you to both collect and send packages.

It is always advisable to offer different options so that the customer can choose the one that best suits them and optimize their online shopping experience.

You have already seen that not many resources are needed to improve the online shopping experience in your store. Be attentive to your client, inform him whenever necessary, keep him excited and satisfied with his purchase, and never forget your relationship, because it is a very special relationship.

Tips to Optimise Your PC Performance

Our computer systems can be compared to the cars that we drive, they must be maintained and on a regular basis in order to ensure that they run optimally. Over time, it’s common for our systems to accumulate a considerable number of unneeded/unused files, applications, and tools, these programs may have been picked up from the internet or they may be something you installed many months or even years ago. All of these things over time have a negative effect on the performance of our computers. However, the good thing is that there are a number of things that you can do to restore the health of your system.

How to Improve PC Performance

Here are a number of tips that you should follow in order to enhance the performance of your computer:

Check for Computer Spyware, Viruses and Malware

Malware or Spyware are small malicious programs that are designed to do harm to your system, they are just as capable of causing harm to your system as your standard virus is. These small programs are able to get onto your computer without your knowledge and cause a great deal of damage. The general purpose of your average spyware program is to spy on whatever the computer user does on the system, sending all of the data that it’s logged back to the creator of the spyware, who typically are fraudsters and hackers out to steal the personal information of your average computer users. The information that they are able to obtain, can be anything from credit card details to username and passwords, typically anything of real value to you.

Although malware and spyware can be used interchangeably, malware is somewhat different in that they tend to be a lot more disruptive to your computer. Spyware is typically unable to act on itself, whereas the moment malware gets on your computer, it immediately goes to work. Malware is capable of completely crippling your system, one very familiar malware that people tend to get is the redirect virus, which basically redirects all your search engine traffic to malicious websites, that are usually laced with viruses. Thus, it’s in your best interest to ensure that neither spyware nor malware gets onto your system; this can be done by running a full scan of any antivirus program you have installed on your computer.

Another side effect of spyware is the toll that it’s able to take on the performance of your computer. It’s also capable of prohibiting you from running certain programs, effectively barring you from doing anything constructive on it; this is usually done while it’s destroying the integrity of your operating system. Therefore, you should also run a spyware remover in addition to the antivirus scan, just to ensure your computer is completely cleaned.

Defrag Your Hard Drive

Hard drive maintenance is something that the average user really things about. The vast majority of computer users typically do not take the time to either maintain or clean their hard drives, however when their operating system starts to act up, they ironically get really angry. Defragging a hard drive has become the conventional solution to fixing sluggish or slow systems, so it’s notwithstanding that it’s typically one’s first recommendation. Hard drives become fragmented as a result of all the files being written to it and erased over time; it’s a process that leads to the hard drive slowly deteriorating in performance.

Whenever you install a new program on a hard drive, portions of the hard drive allocated for it. Over time, as you uninstall programs, and put new ones on, free allocated units begin to spring up all over the hard drive. This leads to data being spread across the entire drive, resulting in the hard drive having to do more work in order to access data for specific programs.

This process of defragmentation has a negative effect on the writing speed of the hard drive, but it also has a negative effect on the actual components of the drive, essentially decreasing the drive life. Fragmentation is a process that cannot be avoided; however, newer hard drives are designed to reduce its effects. Using a storage capacity hard drive is one of the most effective ways to avoid having data being spread across the entire drive. If you ensure that at least 30% of the hard drive is made up of free space, then you can be sure that whenever you assign new data to the drive, it will be stored sequentially. Newer hard drives also have much larger buffers, which helps speed up the reading and writing process.

There are a number of different programs that you can use to defrag your hard drive, however, for the sake of simplicity; I recommend you use the built-in Windows Disk Defragmenter, which you can find in System Tools.

Repair Your Registry

If you don’t know what the registry is, it’s basically an area of the computer where all the configuration settings data is stored. However, over time, as you install more and more programs, it can become corrupted. The registry is also prone to containing data that is no longer of any use, like the settings of a program that you have already uninstalled. When you scan and repair the registry, you’re essentially ironing out all of these issues, which all ultimately affect the performance of your computer.

Remove Unnecessary Programs from Startup

If during the boot-up phase, you have a tone of programs loading up at the same time, then you’ll be made to wait a considerable length of time before your system becomes accessible to you. However, the workaround would be to switch off those programs which you feel, quite frankly have no business loading up during boot up. You can do this by running Microsoft Configuration Utility and uncheck the services that you think your computer can do without.

Free Up Hard Drive Space

Today, hard drives are available in considerably large storage capacities, with purchasing a new hard drive for your computer becoming a more cost-effective approach, as each day passes, but despite all of that, your hard drive will still eventually vanish. If you like to surf the internet, visiting the lost of web pages and downloading and installing applications, then a lot of temporary files will be stored in your internet temp folder, and in some cases, it may prove difficult for you to remove them. Having to think about which files you should delete and which ones you should keep, can prove to be quite a strenuous tasks, as a result, I put together a number of methods that you can use to free up hard drive space.

1. Use Windows Disk Cleanup

If you use a Windows-based operating system, then go to My Computer, access the Properties of your hard drive and click on Disk Cleanup. Once the application has loaded up, it will give you a list of all the files that you can delete in order to conserve hard drive space. Just select the file types that you know you do not need, then click on OK, once you’ve done that, the operating system will ask you to confirm your choice.

This is a process that you should carry out for all the hard drives in your computer. Another way to access this tool is from System Tools.

2. Empty Your Recycle Bin

Make sure that you’ve emptied your recycle bin that no files exist in it. After you’ve emptied your recycle bin, it may also be a good idea for you to defragment your hard drive. This can be done by using Windows Disk Defragmenter, found in system tools.

3. Uninstall Unneeded Applications

To do this, you will have to access Add/Remove Programs, which can be found in your control panel. Once you’ve loaded the applet up, simply scroll through the list of applications on your computer, programs such as browser add-ons and toolbars are not really needed, so you can delete them. This activity will not only help you free up hard drive space, but it should also help you increase the performance of your computer.

4. Empty Your Temporary Internet Folder

All the browsers you can use today are built around the same architecture, they all use temporary folders. So the objective is for you to do one or two things, either you can configure the internet browser to automatically erase the contents of the folder on a given day or when it reaches a certain file size. Or you can opt to delete the contents of this folder manually. Ideally, you’d want to set it so it’s done automatically, but assuming you haven’t already done that, you should load up your browser and empty all your browsing data.

5. Remove Unused Windows Components

It’s possible for you to add and remove windows components that you no longer use. This can be done by loading up Add/Remove Programs, which you can find in the control panel. From here, you can opt to remove components such as the Games folder or certain Internet Self Hosting components that you either do not need or have never used. This is a nice little way of freeing up some space and ultimately enhancing the performance of your computer.

Automatic Software Updates

There are tons of applications out there like Microsoft Office that have updates for it released on a regular basis. This also includes updates for your operating system. By installing these updates it will not only increase the security of your computer, but it will also enhance its performance.

Other Products & Methods

Purchase Additional Products

There are also various additional products that you could consider, like adapters and USB hubs, which are capable of speeding up your computer. These kinds of devices are designed to ensure that you get the most out of any external device that you decide to add to your computer, so that’s definitely something that you should consider.

Plug Your Laptop In

If you’re using a laptop computer, then one thing you should be aware of is that when it’s not plugged in, the device uses less power. So one method that you can use to gain a little more speed out of your laptop computer is to plug it into the mains, where possible.

Upgrade Your Memory

If you purchased your computer brand new from the shop, then it’s likely that it will have some free slots for additional memory expansion. Thus, you should consider adding more RAM to it. Adding memory is a sure-fire way of increasing the performance of your system, whether it’s for gaming or running standard applications.

Dust Your System

One thing you’ll want to do is ensure that your computer is regularly cleaned. If too much dust builds up inside your computer, it can have a detrimental effect on the performance of the components. To dust the computer, you can use either a small vacuum cleaner or compressed air.

Check Cable Connections

Sometimes a loose connection can result in degraded system performance. Thus, it’s important that you check all your cable connections to ensure that they are securely in their slots. You may also want to check your internet connection, just to be sure that things are running as they should.

Python Interview Questions

Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python’s design philosophy emphasizes code readability with its notable use of significant whitespace. 

Nowadays the popularity of python is increasing day by day. Python is easy to learn and has vast libraries. In the field of Machine Learning, Deep Learning and Artificial Intelligence Python are the top priority in the implementation tool.  You can find on google the trends of top programming languages.

Since the demand and popularity are on top, so the career opportunity in Python programming and related fields is high. Keeping this in mind we have created a set of some useful Python Interview Questions and Answers, so that one may find a proper guide for an Interview. 

Python Interview Questions are very useful when you are going for an Interview for the designation of Python Developer or Machine Learning or any Related fields to Python. These python interview questions and answers are equally useful for freshers and experienced.

While representing this set of questions along with answers we hope that they will be useful for visitors.

What is Python?

Python is an Interpreted programming language with objects, modules, threads, exceptions and automatic memory management. The benefits of pythons are that it is simple and easy, portable, extensible, built-in data structure and it is open-source.

What are the key features of Python?

  • Python is an interpreted language. That means Python does not need to be compiled before it is run. 
  • Python is dynamically typed, this means that you don’t need to state the types of variables when you declare them or anything like that. 
  • Python is well suited to object-orientated programming in that it allows the definition of classes along with composition and inheritance. 
  • In Python, functions are first-class objects. This means that they can be assigned to variables, returned from other functions and passed into functions. Classes are also first-class objects
  • Writing Python code is quick but running it is often slower than compiled languages. Fortunately,Python allows the inclusion of C based extensions so bottlenecks can be optimized away and often are. 

What type of language is python? Programming or scripting?

Python is capable of scripting, but in a general sense, it is considered as a general-purpose programming language.

What is PEP 8?

PEP 8 is a coding convention, a set of recommendations about how to write your Python code more readable.

What are Python packages?

Python packages are namespaces containing multiple modules.

What is the difference between abs () and fabs ()?

abs() is a built-in function that works with integer, float and complex numbers also.

fabs() is defined in the math module which doesn’t work with complex numbers.

How Python is interpreted?

Python is an interpreted language because Python program runs directly from the source code. It converts the source code that is written by the programmer into an intermediate language, which is again translated into machine language that has to be executed.

How memory is managed in Python?

Python has an awesome feature of memory management. The following points will explain memory management in python:

  • Python memory is managed by Python private heap space. All Python objects and data structures are located in a private heap. The programmer does not have access to this private heap and the interpreter takes care of this Python private heap.
  • The allocation of Python heap space for Python objects is done by the Python memory manager. The core API gives access to some tools for the programmer to code.
  • Python also has an inbuilt garbage collector, which recycles all the unused memory and frees the memory and makes it available to the heap space.

 

What are the tools that help to find bugs or perform the static analysis?

PyChecker is a static analysis tool that detects bugs in Python source code and warns about the style and complexity of the bug. Pylint is another tool that verifies whether the module meets the coding standard.

 

What are Python decorators?

A Python decorator is a specific change that we make in Python syntax to alter functions easily.

 

What is the difference between list and tuple?

The difference between list and tuple is that the list is mutable while tuple is not. Tuple can be hashed for e.g as a key for dictionaries.

 

How are arguments passed by value or by reference?

Everything in Python is an object and all variables hold references to the objects. The reference values are according to the functions; as a result, you cannot change the value of the references. However, you can change the objects if it is mutable.

 

What is Dict and List comprehensions are?

They are syntax constructions to ease the creation of a Dictionary or List based on existing iterable.

 

What is the built-in type does python provides?

There are mutable and Immutable types of Pythons built-in types Mutable built-in types

  • List
  • Sets
  • Dictionaries

Immutable built-in types

  • Strings
  • Tuples
  • Numbers

 

What is namespace in Python?

In Python, every name introduced has a place where it lives and can be hooked for. This is known as a namespace. It is like a box where a variable name is mapped to the object placed. Whenever the variable is searched out, this box will be searched, to get the corresponding object.

 

What is the difference between deep and shallow copy?

Shallow copy is used when a new instance type gets created and it keeps the values that are copied in the new instance. Shallow copy is used to copy the reference pointers just like it copies the values. These references point to the original objects and the changes made in any member of the class will also affect the original copy of it. Shallow copy allows faster execution of the program and it depends on the size of the data that is used.

A deep copy is used to store the values that are already copied. The deep copy doesn’t copy the reference pointers to the objects. It makes the reference to an object and the new object that is pointed by some other object gets stored. The changes made in the original copy won’t affect any other copy that uses the object. Deep copy makes execution of the program slower due to making certain copies for each object that is been called.

 

What is lambda in Python?

It is a single expression anonymous function often used as an inline function.

 

Why lambda forms in python does not have statements?

A lambda form in python does not have statements as it is used to make a new function object and then return them at runtime.

 

Does python support multiple inheritances?

Multiple inheritances mean that a class can be derived from more than one parent class. Python does support multiple inheritances, unlike Java.

 

What is a pass in Python?

Pass means, no-operation Python statement, or in other words, it is a place holder in a compound statement, where there should be a blank left and nothing has to be written there.

 

What is Polymorphism in Python?

Polymorphism means the ability to take multiple forms. So, for instance, if the parent class has a method named ABC then the child class also can have a method with the same name ABC having its own parameters and variables. Python allows polymorphism.

 

What is encapsulation in Python?

Encapsulation means binding the code and the data together. A Python class is an example of encapsulation.

 

How do you do data abstraction in Python?

Data Abstraction is providing only the required details and hiding the implementation from the world. It can be achieved in Python by using interfaces and abstract classes.

 

How to use access specifiers?

Python does not deprive access to an instance variable or function. Python lays down the concept of prefixing the name of the variable, function or method with a single or double underscore to imitate the behavior of protected and private access specifiers.  

 

In Python what are iterators?

In Python, iterators are used to iterate a group of elements, containers like a list.

 

What is the unit test in Python?

A unit testing framework in Python is known as a unit test. It supports the sharing of setups, automation testing, shutdown code for tests, aggregation of tests into collections, etc.

 

Explain what Flask is and its benefits?

Flask is a web microframework for Python based on “Werkzeug, Jinja2 and good intentions” BSD license. Werkzeug and Jinja2 are two of its dependencies. This means it will have little to no dependencies on external libraries.  It makes the framework light while there is a little dependency to update and fewer security bugs.

A session basically allows you to remember information from one request to another. In a flask, a session uses a signed cookie so the user can look at the session contents and modify it. The user can modify the session if only it has the secret key Flask.secret_key.

 

In Python what is slicing?

A mechanism to select a range of items from sequence types like list, tuple, strings, etc. is known as slicing.

 

What are the generators in Python?

The way of implementing iterators are known as generators. It is a normal function except that it yields expression in the function.

 

What is PYTHONPATH?

It is an environment variable that is used when a module is imported. Whenever a module is imported, PYTHONPATH is also looked up to check for the presence of the imported modules in various directories. The interpreter uses it to determine which module to load.

 

What is type conversion in Python?

Type conversion refers to the conversion of one data type into another.

int() : converts any data type into integer type

float() : converts any data type into float type

ord() : converts characters into integer

hex() : converts integers to hexadecimal

oct() : converts integer to octal

tuple() : This function is used to convert to a tuple.

List out the inheritance styles in Django.

In Django, there are three possible inheritance styles:

  1. Abstract Base Classes: This style is used when you only want the parent’s class to hold information that you don’t want to type out for each child model.
  2. Multi-table Inheritance: This style is used If you are sub-classing an existing model and need each model to have its own database table.
  3. Proxy models: You can use this model, If you only want to modify the Python level behavior of the model, without changing the model’s fields.
