A computer is a general purpose device that can be
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 (CPU) and some form of.
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.
