reference word :
A computer, like any other machine, is used because it does certain jobs better
and more efficiently than humans. It can receive more information and process it
faster than any human. The speed at which a computer works means it can
replace weeks or even months of pencil-and-paper work. Therefore, computers
are used when the time saved offsets their cost, which is one of the many
reasons they are used so much in business industry, and
research.
