Computer science

Computer science is the scientific and practical approach to computation and its applications. It is 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. Still other fields focus on challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, while the study of computer programming itself investigates various aspects of the use of programming language and complex systems. Human–computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans.

Computer Sciences Corporation

Computer Sciences Corporation (CSC) is an American multinational corporation that provides information technology (IT) services and professional services. Its headquarters are located in Falls Church, Virginia. CSC has 74,000 employees in over 70 countries. Its clients include commercial enterprises and the U.S. federal government, as well as state, local and non-U.S. government agencies.

In September 2009, when Xerox acquired Affiliated Computer Services, CSC became the only remaining major "hardware vendor independent" IT service provider with headquarters and major operations in the U.S.

CSC has been a Fortune 500 Company since 1995, ranked 185 in the 2014 rankings. The company also figures in the Forbes Global 2000 list.

History

CSC was founded in April 1959 in Los Angeles, California, by Roy Nutt and Fletcher Jones. CSC initially provided programming tools such as compiler and assembling software.

In the 1960s, CSC provided software writing services to major computer manufacturers like IBM and Honeywell and secured their first contracts for the U.S. public sector with NASA (among others).

Computer

A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.

Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.

Mechanical analog computers started appearing in the first century and were later used in the medieval era for astronomical calculations. In World War II, mechanical analog computers were used for specialized military applications such as calculating torpedo aiming. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).
