a computer is what?? it is simply a machine made of hardware??but why we need computer....the answer is we need computer to perform computation on a specific task....how this computation will occur in the computer is defined by a set of rules ...to understand these rules ,we need to study theory of computation....

theory drives practice and practice drives theory....to make efficient machines for computation tasks we need to study theory of computation.

Its a theory specially addressed to computing students and programming developers.

No, theory of computation is purely in the realm of computer science theory. It deals with the fundamental computational ideas underpinning computer science. Some computer scientist never even fully learn the subject. As a hacker, unless a very good one, who wants to delve more into computer science, there is no requirement to learn it.
