Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to, information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.
Its fields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory (which explores the fundamental properties of computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications. Other fields still focus on challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, while the study of computer programmingitself investigates various aspects of the use of programming language and complex systems. Human–computer interactionconsiders the challenges in making computers and computations useful, usable, and universally accessible to humans.

- In recent years, America has accomplished astounding goals with the use of increasingly elite computer technology. We put Armstrong on the moon in July of 1969 (Zona, par. 3), and in 2004 we created a social networking site that became world-wide (“Facebook”, par. 1). There are those who suggest that America has become too dependent on technology, but these objectors have no alternative to offer. Indeed, what would it be. Even though it is true that a highly skilled hacker could conceivably cause the demise of our great country by delivering classified information to an enemy nation, state-of-the art computer technology is essential to our way of life and is here to stay....
