Computer science (or computing science)

Computer science (or computing science) is the study of the theoretical foundations of and , and of practical techniques for their implementation and application in sform information; the fundamental question underlying computer science is, "What can be (efficiently) automated?" Computer science has many sub-fields; some, such as, emphasize the computation of specific results, while others, such as , study the properties of . Still others focus on the challenges in implementing computations. For example studies approaches to describing computations, whi applies specific to solve specific computational problems, andfocuses on the challenges in making computers and computations useful, usable, and universally accessible to .

The general public sometimes confuses computer science with vocational areas that deal with computers (such as ), or think that it relates to their own experience of computers, which typically involves activities such as gaming, web-browsing, and word-processing. However, the focus of computer science is more on understanding the properties of the programs used to implement software such as games and web-browsers, and using that understanding to create new programs or improve existing ones
