The computerA computer is a general purpose device that can be

programmed to carry out a set of arithmetic or logical operations. 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 that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result

of operations saved and retrieved.
