What is Computer Science Engineering all about? Discover the scope of Computer Science Engineering



Computer Science is one of the most sought after courses by Indian students, thanks to the software and IT boom of the past two decades. Apart from putting India on the global map, computer science has pretty much changed the whole landscape of how people live. Right from social media to the genomics revolution, computer science has played a central role in many of the greatest technological innovations and developments of the 21st century. Since this field is hugely popular among Indian students, admissions to prestigious universities such as IITs, NITs and IIITs are very competitive. On the other hand, computer science is all set to grow in an unparalleled manner in the coming few years, thereby creating a lot of opportunities for students. Read on to discover more about this field in-depth.


Most students take up computer science as their undergraduate major because of the huge number of job opportunities in India’s software and IT industry. But, there is so much more to computer science than just software and IT. A degree in computer science engineering exposes students to both theoretical as well as practical aspects of computer science. By the time undergraduate studies are over, you would have barely scratched the surface of this vast and burgeoning field. Over the past two decades, computer science has evolved rapidly and has produced remarkable acceleration and innovation not just in the world of internet and artificial intelligence but also in diverse fields such as banking, electronics, biology, chemistry, medicine and healthcare, to name a few. In short, computer science has invaded every other field and good programming and coding skills has become a basic requisite.

Since computer science is based on the fundamentals of mathematics, computer science students develop critical reasoning and complex problem solving abilities that will help them in all walks of life. Some of the sub disciplines of computer science are theoretical computer science, theory of computation, information and coding theory, algorithms and data structures, programming language theory, formal methods, applied computer science etc. and students can specialize in any one (or more) of these areas during their undergraduate or graduate studies. Presently, job opportunities are great for computer science students all over the world. Even during difficult times such as recession, a highly skilled and bright computer science professional will always be in demand.

This question can be very confusing indeed. If you take a look at the various programs offered by the IITs, IIITs, BITs, NITs etc. you will realize that they offer only computer science engineering and no course titled information technology. Yet, there are many other universities, such as Anna University and Mumbai University, that offer information technology along with computer science and other courses. If you take a look at the curriculum for both computer science and information technology in these universities, this is what you will find:

Common courses between CS and IT are as follows: Data structures, database management system and concepts, probability and queuing theory, design and analysis of algorithms, operating systems, software engineering, object oriented analysis and design, computer graphics and multimedia.

Courses in CS: Principles of computer engineering, programming using C++, algebra and number theory, electronic devices and circuits, java and internet programming, computer architecture, electrical engineering and control systems, microprocessors and microcontrollers, systems software internals, theory of computation, communications and computer networks, artificial intelligence, compiler design, programming paradigms, digital signal processing - algorithms and applications, principles of management, mobile and pervasive computing, parallel programming, security in computing.

Courses in IT: Information technology essentials, web technology, discrete mathematics, programming and data structures-II, computer organization, formal languages and automata, distributed system, integrated programming, embedded systems, information management, mobile computing, computer networks, data analytics, principles of human computer interaction.

From the above distribution of courses, IT degree is more inclined towards the applications of computer science such as the design, development and maintenance of computer systems and networks for processing, storing, managing and distributing large amounts of data. CS, on the other hand, gives equal importance to theoretical concepts as well as the practical applications of computer science.

At the end of the day, during placement sessions, most companies do not differentiate between the two fields and the same designation will be offered to both CS and IT students. Also, in most universities, there is not much of a difference in the syllabus of both CS and IT, barring a few courses.

This depends on which area of computer science you are interested in. If you want to specialize in the theoretical aspects of computer science, you have to be extremely good in mathematics as it is the foundation for theoretical computer science (TCS). If you want to do your PhD in computer science or get into research, then you will be expected to have strong quantitative skills. However, if you want to become a programmer or developer in an IT company upon completion of your undergraduate studies, you don’t have to excel in mathematics and sound logical thinking skills will hold you in good stead. All you have to do is write organized and efficient code, which will come with hard work and experience.
