Ø 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.
Ø
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.
