Computers grew rapidly and widely used through out the world.They are used
to deal with many tasks due to their various potential.Therefor,they have much
influence on our life.Their impact can be classified into three catogories;
communication,facilities and medical care.

seem to be gradually destroyed. Computer can bring people closer together and
facilitate contacts between them.For example,people can comunicate with others
worldwide by using e-mail.It saves their time compared with letter.

medical information.Physician and nurse can access to this data easier which result in
decreasing the process of operation.

are used to manage these tasks.For example,in laboratory, medicine invention and
some operations,some tasks are done by computer instead of people.Therefor,it saves
time for both patients and physicians which result in reducing delay action.
In conclusion,computer plays important role on human behaviors.It provides
