A computer is a general purpose device that can be programmed
to carry out a finite 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.
computer consists of at least one processing element 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.
The first electronic digital
computers were developed between 1940 and 1945 in the United Kingdom
and United States. Originally they were the size of a large room,
consuming as much power as several hundred modern personal computers
(PC).
