What is Computer Science?

In its most general sense, computer science (CS or compsci) is the study of computation and information processing, both in hardware and in software.

In practice, computer science includes a variety of topics relating to computers, which range from the abstract analysis of algorithms, formal grammars, etc. to more concrete subjects like programming languages, software, and computer hardware. As a scientific discipline, it differs significantly from and is often confused with mathematics, programming, software engineering, and computer engineering, although there is some degree of overlap with these and other fields.  (taken from Wikipedia, the free encyclopedia)
