Computer is one of the inventions of the 20th century that changed the world greatly. The first computers of the 1940s were enormous. But now they are almost in every family and in every office building.
Most machines do only one job, some are multifunctional (e.g. а ТУ set + DVD player). But no device is as multifunctional as computer. Computers are found everywhere and used in every sphere of life. Computer is used at school: children watch films, presentations and web pages. This helps them to study effectively.
Computers also have some disadvantages. As computer is а complicated device, one small breakage may stop its work. Besides, computers become more and more complicated, and much effort is required to learn how to work with them.
A computer is а multifunctional device, as we already know, so it can be used both to do work and to entertain oneself. Children often fall prey to computer and Internet: they play computer games, spend their free time chatting with friends on the Internet and doing practically nothing.
То crown it all, computer is а good device like many others, designed to help people. But it's our own free will that lets us use it in order not to waste time but to get best results.
