Do you want to know- Why Study Computer Science in 2021 and why it is so important to learn Computer Science in 2021.

As you are landing on this article that means you are obviously wondering over Internet about why study Computer Science or which topics should you learn in Computer Science or what are the benefits of learning Computer Science ?

The computer is playing a great role in our lives, it makes our life very easy, better, faster and more connected.

As we live in a digital age, it is a necessary to have and use a computer in daily life to live.

Computer science & technology are part of just about everything that touches our lives like online learning, banking, business, airlines, railways, weather forecast, medical diagnosis, communications,  entertainment  and the list is endless.

Today’s world is going to become more computers driven world, such as self driven vehicles, robots, drones and digital door locks etc are becoming real possibilities because of computer science and its advancement. 

But this did not happen by magic. We arrived here because of the hard worked & brilliant minds of Computer Scientists, Engineers & programmers, who took their passion for technology and used technology to create gadgets and computer programs which help us every single day.

According to Bureau of Labor Statistics, demand for computer and information technology occupations will rise significantly from 2019 to 2029. The BLS projected 11% job growth rate in the Computer Science field during the time period, which is significantly faster rate than the national average for all occupations.

It means “learning computer science will help us to live in the future world we are creating”. As technology continues to move to the forefront in our society, jobs requiring computational skills are soaring. Therefore, having computer science skills will enable you to succeed in the workplace of the future.

Presently, many school/ colleges/ professional institutes are running various levels of training / courses i.e. Diploma, UG & PG in Computer Science, Computer Application, Computer Engineering and Information Technology.

But, in my point of view, as of now, most of the institutions are providing various courses / training on the line of traditional and outdated way, which is very rare use and related to real world works/ requirements.

As I am an Ex student of Computer Science/ Information Technology and attended the Diploma, UG & PG in Computer Science from various universities/ institutes of India.

After completion of my Post Graduation in Computer Science, while I was start working for real life project, I feel that traditional learning did not work much for me, so I was decided to add more knowledge to my portfolio to stand on crowd.

Then, I continued journey of my study with other experts of computer science and professional programmers through various online and off line resources to expend my knowledge. 

As per my experience, it is feel that many interested people and students are always searching on Internet about why study Computer Science or which topics should learn in Computer Science or what are the benefits of learning Computer Science.

That’s why actually I am writing and prepared a master guide on computer science, where I explore & uncovered the following:

  • What are the major fields available in Computer Science
  • How to choose your career paths in Computer Science
  • Why study Computer Science in 2021 master guide

What are the major fields available in Computer Science?

Computer Science- is the study of computers and computing concepts. Computer science is mainly divided in four areas:

Computer Architecture

Computer architecture is the science of interactions among a computer’s hardware components to meet the functional requirements along with acceptable performances. In simple word, what components interconnected in what ways will produce what performance is the subject of Computer Architecture.


Computer programming language is a language comprising vocabulary and a set of instructions used to write computer programs which generally give instructions to computer to perform a specific task or get a desired output.

Computer Networks & Security

Computer network transporting information directly from computer to computer rather than through a human intermediary. A group of computers and other devices connected together is called a Network, and the connected computers sharing resources is called networking.

Artificial Intelligence.

Artificial Intelligence is the area of computer science concerned with study and creation of intelligent computer systems & machines that exhibit the characteristics we associate with intelligence in human behavior-understanding language, learning, reasoning and solving problems. 

How to choose your career paths in Computer Science?

Computer science will open many avenues for your bright future. You just need to choose as per your interest:

  • If you want to build a computer, you can go with computer architect/ hardware engineering.
  • If your dream to gift a brand new software to world, you can go with programming.
  • If you want to develop website/ game/ application, you can also go with programming.
  • If you want to stop cyber crime, you can go with computer networks & security.
  • If you want to make a brand new robot, you can go with artificial intelligence.
