What is computer science?

Let us first break down the term ‘Computer Science’ into two. Once we grasp the meaning of science, it will become much easier for us to explain what Computer Science means.

Science refers to the act of conducting a thorough study of a subject. It involves the processes of observation as well as hands-on experimentation and testing in order to gain complete knowledge about the subject. That makes Computer Science an exhaustive study of everything related to computers.

Computer science is essentially the study of how to translate the language of machines into a more easily understandable and usable language for people. The field uses the theory of information and computation in the interrogation and calculation of information.

 

This makes it possible to communicate, analyse, process and represent information effectively and efficiently.  The discipline deploys logical thinking approaches with a view to developing elegant and practical solutions. Computer science is categorised as a STEM subject.

You can divide Computer Science into two broad categories – theory and programming. In order to be a computer scientist, you need to be able to do two things:

  1. First, you must understand precisely how a computer works.
  2. Then, you apply whatever theory you learnt to efficiently communicate with and make better use of computers via programming.

Let us explain this to you in simpler terms.

Suppose you want to bake a cake. Would you be able to do that if you did not know about the ingredients? Of course not. You must know how much flour, baking powder, sugar or eggs would go into your cake. Knowing the recipe is the theoretical part.

Next comes the process of baking itself. You mix all the ingredients into a batter and put it into the oven. After some time, your cake will be ready to eat!

That is how Computer Science works too. So what are the ingredients of Computer Science?

Most Computer Science programs cover the following subjects in varying levels of detail/depth:

  • Mathematics
  • Electronics
  • Physics
  • Programming
  • Other engineering electives
