Computer Science Definiton

This article or section contains full references and citations to a list of references or external links. However, verifiability is not entirely clear because it lacks enough footnotes.
You can help by editing and introducing more precise citations (read here about how to add).

The computer science are those that include the study of the theoretical foundations of information and computation and their implementation in computer systems. There are several fields or disciplines in the Sciences Computer Science or Computer Science, some emphasize the computation of specific results (such as computer graphics), while others (such as computational complexity theory) relate to properties of algorithms used to perform computations. Others meanwhile are focused on problems that require the implementation of computations. For example, studies of the theory of programming languages ​​describe a computation, while computer programming applies specific programming languages ​​to develop a solution to a particular computer problem. The information relates to automatic processing of information in a useful and timely. Do not confuse the theoretical nature of this science to practical aspects such as the Internet.

According to Peter J. Denning, the key issue on which computer science is, "What can be (efficiently) automated?".
