Describe some useful ways in which computers have

Computers have become increasingly important and
popular. Could you describe some useful ways in
which computers have so far contributed to our
modern life?

The most wonderful invention of the machine age, the
computer, has been used since 1946. Since its
appearance, the computer has contributed to mankind
many useful ways in every aspect.

First of all, in the accounting domain: with lightning speed
and perfect accuracy, the computer can do simple
calculations such as: addition, subtraction, multiplication
and division marvelously. A computer can work 500,000
times faster than a man can do with pencil and paper.
Calculations which would have taken days become a
matter of minutes with computers.

Then in the study and research of scientists, historians
and sociologists not only can the computer gather facts
but it can also store them as fast as they are gathered and
then can pour them out whenever they are needed. In this
way, the computer is really a high-powered memory
machine capable of answering all problems and questions.

Next in the navigation and aviation scopes: with the
computer, pilots and sailors can avoid all dangers on their
itinerary. It helps them direct their flights and voyages from
this city to another one, control airspeeds and altitudes

when their planes land or take off. How could NASA solve
all the problems of the space shuttles without its
computers.

Finally in the constructing and designing fields: besides
gathering and storing information the computer can solve
complicated problems that took man months to do. They
have been used by building companies. From the
architect’s original plan, the computers can derive new
plans according to a new type of environment, the cost of
building and so on…

To sum up, we dare say that there is practically no limit to
what computers can do and their contributions to our
modern life ar
