Digital Transformation is changing the mode of the core business process of a company/ organization/institute from manual to digital by leveraging technology and data. In the education sector, it can be defined as changing the mode of learning and teaching from physical mode to online mode. Yet the physical model of education is used as the primary source of education but the advancement in technology has increased and revolutionized the world’s education system.

The whole world has been affected by the global COVID-19 pandemic. It has a tragic effect on every sector of life. Economies were collapsed. It has affected the education department both in developing and underdeveloped countries. The educational institutes were closed worldwide due to lockdown. Although some of the educational institutions were using technology solutions but it wasn’t a common practice. After the outbreak of the pandemic, the importance and necessity of technology in the educational industry came into the view.

The digital transformation has affected the common classrooms and also the way how teachers reach the students. The use of online learning has only the way that digital transformation has impacted students and classrooms trends. Let’s discuss the impact of digital transformation in education industry.

Improved accessibility and access

The greatest impact of digital transformation in education is improved access and accessibility to schools, colleges, universities, lessons, and even degree programs for students of all ages. Accessibility and access also continue to grow from a geographic perspective. Online learning opportunities allow students to access degree programs and schools that are remote to them. This removes the limitation within the geographic areas. This trend has a great impact on the education system as it is improving the flexibility for some courses, or even programs, in higher education.

Personalized learning approaches

Personalized learning approaches have also been one of the reasons that impacted the revolution in the digital transformation in education. This approach provides a number of benefits to students and institutions.  In this approach, the students are allowed to learn in a way that fits their own learning approaches, so that students can absorb and retain critical information. This approach empowers them to move forward in their education.

Virtual Reality

In the world of education, virtual reality can provide a chance to experience the material they learn before they actually move into real-world applications. This can help students feel better and prepared for their careers and to complete their education.

Cloud-based learning opportunities

The cloud offers students and teachers to connect virtually from anywhere. When the pandemic hit all over the world, this accelerated the potential use of these types of applications. The teacher began using a variety of different platforms to conduct the class and post the material regarding the class, i.e., class notes, etc. This platform provided a lot of opportunities, they enable the streaming of lectures, and students can submit their applications through many applications and keep track of their syllabus. This trend after the pandemic has left a huge impact on digital transformation in the education world.

Tracking of Student results

One impact of digital transformation in education is that it provides a reality-based way to monitor the student’s progress. Technology plays an important role to let the teacher and parents track the progress of the student.

Improved results with data analytics

Schools may use analytics to monitor and enhance the results. Using analytics it will help to clearly understand how a student missed a term. Technology will help us to diagnose these shortcomings much more easily than a teacher might do in 30+ classrooms.

Cooperative Learning

Collaboration is forced by digital learning. Teachers can divide the students into groups and handle the groups through the learning platforms.

Time-Saving

Digitalization is a great saver in the world today where time is money. Digital training is a rescue for students from even the farthest parts of the country in this scenario.

Final Words

By digitalizing the experience of learning, both students and teachers may improve their skills in order to create an active educational process. Digital transformation in education can be applied in many respects, from online learning to intelligent schooling, student assessments, customized learning experiences, and online examinations.

In recent years, blockchain technology has made significant strides in both development and use, and there is no indication that this trend will slow down any time soon. It’s now or never to prepare for a financial and social upheaval that will radically transform the way we do business. It’s a pity that the general public still has so little understanding of blockchain technology.

This kind of digital money technology lies at the heart of the operation of coins such as Bitcoin. As a consequence, many people are unaware of the potential benefits of blockchain technology for themselves, their companies, or even society as a whole.

So, what does the future hold for the technology known as blockchain? What are the predicted results in this situation?

The future of Blockchain and its impact on the world

Thanks to recent breakthroughs in blockchain technology, a decentralized, trustless internet, total transaction transparency, and a plethora of other possibilities are now within reach. As far as I’m concerned, blockchain is here to stay, and I think it will be a vital instrument for the advancement of humanity in the future. Reid Hoffman, co-founder and Executive Chairman of LinkedIn, is a successful entrepreneur.

Deloitte’s 2021 Global Blockchain Development Survey polled CEOs, and more than two-thirds of those polled expected that digital assets would be a viable alternative to fiat currencies within five to 10 years. If you want to become involved in the blockchain industry or keep up with the newest technological breakthroughs, starting a blockchain development company is a great way to begin your journey.

In addition, here are a few instances of how blockchain will alter the course of human history:

The emergence of Non-Fungible Tokens

Bitcoin and other cryptocurrencies will continue to be one of the most significant blockchain use cases for the foreseeable future. Even more exciting is the creation of non-fungible tokens in blockchain technology, which have the potential to be very valuable (NFTs).

You may now acquire and exchange digital assets that are modeled like real-world items thanks to the advent of NFTs. Non-fungible assets (NFTs) are assets that cannot be replaced or swapped; they can only be purchased, sold, or given away by the person who originally created them.

For the first time, NFTs have the potential to be utilized to create a whole new class of digital valuables, ranging from rare artwork to one-of-a-kind footwear and clothing. They may also be used as a replacement for items found in virtual worlds.

Fastest monetary transactions

Because of the secure and decentralized nature of blockchain technology, it is almost difficult for hackers or other malicious actors to meddle with transactions. The fact that blockchain-verified data is so secure and dependable means that transactions may be performed far more rapidly than they can presently, without compromising on safety and dependability.

In the banking and financial services industry, there are a variety of reasons for the shift to an all-electronic system of operations. According to predictions, blockchain technology will gain appeal among financial professionals in the next years, with 66 percent of institutions planning to employ blockchain solutions over the next three years.

Furthermore, the future of blockchain in finance will allow us to make transactions at any time of day or night, seven days a week, 365 days a year. As a result of recent technological advancements, businesses, governments, and people may perform transactions at any time and from any place, independent of local banking hours.

The rapid growth of the digital economy

When we connect to the internet, we are now required to identify our identity via the use of passwords and authentication questions. This method may be replaced with a digital identity that is safe, secure, and easy to administrate thanks to blockchain technology.
Your private key cannot be hacked or updated using this approach, which makes it significantly more secure than our current system. The National Institute for Standards and Technology (NIST) is already investigating how blockchain technology may be used to help protect digital identities.
Instead of relying on a specific piece of information that may be guessed or stolen, your digital identity is based on a random set of numbers assigned to each user on a blockchain network.

Real estate buying and selling

The issue of confirming and validating one’s identity has moved to the top of the priority list in the real estate industry in recent years. A buyer must wait before a bank will complete the Know Your Customer (KYC) process on their behalf.
By making it simpler to trace the sources of data, smart contracts, which are constructed on the blockchain, have the potential to simplify the data verification process by streamlining the data verification process. These self-executing contracts have a wide variety of applications, including the processing of loan requests and the authentication of identities, among others. Blockchain technology has various uses in the real estate business, like smart home devices that sync with your lease terms and transparent transaction data. However, there are limitless possibilities for the technology to be used in.

Conclusion

The usage of blockchain technology is increasing noticeably throughout the whole information technology sector, according to recent data. To the general public, blockchain currencies (sometimes referred to as cryptocurrencies) such as Bitcoin and Ethereum are well-known and widely used. Despite the fact that it began as a payment system, the blockchain has developed into much more than just a digital ledger.
Instead of depending on a single central authority, a distributed ledger technology known as blockchain eliminates the need for a third party, such as a typical financial institution, to facilitate transactions. A transactional ledger is made up of a series of data units that are connected together in a chain. The use of an open-source, impenetrable configuration allows for unprecedented openness and accountability. Thousands of computers located all around the world check each record to ensure that it is accurate.

JavaScript is the most popular language in the world. When we write a program in JavaScript and try to run it. Do we know what happens behind the scene? The most basic mechanism that helps to run JavaScript code is known as execution context. Every JavaScript program is run in the execution context. So I will help you to explain the execution context in detail with the help of writing code.

Execution Context

You can imagine the execution context as a container, in which a JavaScript program is run. When we run a program an execution context is created which is known as the global execution context. And one more thing wants to tell, Functions are the heart of JavaScript. You can consider function as a mini-program. And every time the calling of the function a new execution context is created inside the current execution context which is also known as the local execution context.

Parts of Execution Context:

The execution context has two main parts. First, part is used for memory management in which all functions and variables are stored as key-value pairs. The first part is also known as memory management or variable environment. Basically in this part memory is allocated to all the variables and functions. The second part is used to run the code and is known as the code environment or execution environment. JavaScript is a single-threaded language that will run one line at a time. And in the second part of the execution context, the code will run line by line. Now I think it’s enough for the theory part so let’s come and make our hands dirty by writing code.

Example

Let’s see what happens when we run the above code. First of all global execution context is created which is completed in two phases.

Diagram

Phases of Execution Context

Memory Creation Phase

As I said earlier, the first phase is known as the memory creation phase and the second phase is known as the code execution phase. As soon as JavaScript encounters line number 1. So it allocate memory for num1 and store undefined on that you can see the execution context diagram above. When it encounters the second line it again allocates memory for num2 and stores undefined in that. When JavaScript encounters line number 3. Here you can see on line number three the sum function is defined so it allocates memory for the sum function and stores the whole function as it is on that sum you can see it in the execution context diagram above. When JavaScript encounters line number 6 it allocates memory for the result and now you already know what is stored in that. Yes, you are right, undefined is stored in the result. As this is the last line. So memory creation phase is completed.

Diagram

Code Execution Phase

Now code execution phase is started. When JavaScript encounters line number 1 it runs that and changes the value of num1 from undefined to 2. Then line no 2 is executed after that the value of num2 becomes 3. When JavaScript encounters line number 3 because here function is defined on that line so JavaScript skips the whole function and goes to line number 6. On line number 6 we are calling a function and as I said when the function is called a new execution context is created inside the current execution context.

The current execution context is global so the new execution context is created inside the global execution context.

Let’s suppose the name of the new execution context is local. So as you know the execution context is completed in two phases. So local execution context also goes through two phases. The first is the memory creation phase. Now you only consider the two lines number 3 and 4.  In the memory creation phase for n1 and n2 space is allocated and stored undefined you can see the above diagram. There is only n1 and n2 variable on the sum function so the memory creation phase is completed.

Diagram

Now code execution phase is started num1 is passed to n1 so the value of n1 is changed from undefined to the value of num1 which is 2 and after that num2 is passed to n2 so the value of n2 is changed from undefined to the value of num2 which is 3, you can refer the above diagram. After that line number 4 is executed n1 and n2 is added and returned from the function which is 2 + 3 = (5).

Diagram

Because we return from the function so local execution context will be deleted and the value 5 is given to the caller which is on line 6. So now line 6 is run and the result is changed from undefined to 5

After running line 6, now no code is left so the global execution context is also deleted. So, this is all about the execution context. It is very simple.

Hope you find this helpful.

Generics 

Generics are the most important part of java. With the use of generics, you can write generic classes, interfaces, and methods that perform operations on different types of data. The actual type on which they perform the operation is given by parameter. Before the generics, you can write classes, interfaces, and methods which operate on different types of data. But these codes are not type-safe you can explicitly cast these codes into appropriate types if you do a mistake to cast properly then an error occurred. Generics come with type safety. You do not need to worry about the casting in generics. It is implicitly happened by the compiler. Let’s learn the concept of generics and implicit casting with the help of code.

Example

Parameterized Type

The T in angle bracket (<>) is known as parameterized type. Most people think that when they declare a variable of generic code and pass argument in angle bracket suppose Gen a = new Gen, they think a new Gen class is created. But this is not happening actually, Java uses the type erasure mechanism for generics. So, let’s learn type erasure and see what happen behind the scene.

Type Erasure

Actually, when we compile the Gen class the type erasure removed all the parameterized types. The type erasure replaces the parameterized type with the bound. If no bound is specified then the type erasure replaces the parameterized type with the Object. So, after compiling the Gen class. It looks like this;

Actually, when we declare the variable of Gen, suppose we declare Gen iob = new Gen and Gen strob = new Gen both the object is an instance of Gen. But what happens when we call the getob function actually we get the value in the type of Integer if we call this function through iob and the value in the type of String when we call this function through strob. But this function is returning Object in code. So it means down-casting is happening behind the scene. How this happens let’s come and see this through an example:

Example

Output:

So, you see the output v is ‘88’ and str is ‘Dummy String’. But the question arises of how down-casting is performed implicitly because we know down-casting is an explicit process. Actually, in generics, it performs implicitly. The reason behind that when you compile the GenDemo class the compiler appends the code for downcasting in that. The GenDemo class after compile look like that:

See on line number 10 and 18. The compiler ensures the proper down-casting in generic that why generic is type safe. Most people do not know about that but it happens behind the scene.

I hope this material is helpful for you in writing generic code properly. And now I think you guys are clear about the concept and know what happened behind the scene with generics.
