What are some benefits of using a computer?

Nowadays, we cannot do without a computer. It is necessary in almost all spheres of human life: to course ships and airplanes, to manage space stations, to create projects of various buildings and their interiors, to help to draw pictures, to conduct the office work, to print books and magazines and even to write music!

The first electronic machines were invented in order to help a person to make complex mathematical calculations, to store in memory numerous huge formulas. But over time, it turned out that these machines can store and reproduce any other kind of information.

With the development of computer technology, reading lovers no longer need to fill the cabinets with thick books, and music lovers — to pile on the shelves of numerous cassettes. Now you can just buy a few small discs with a lot of information on them.

Thanks to the Internet, the computer has become an inexhaustible source of knowledge for schoolchildren and students. There are many educational games, encyclopedias, dictionaries and so on. That is, the benefits of the computer are obvious and undeniable.

But at the same time, it is necessary to know about the harmful effects of working with it: for example, about such as vision loss, headaches, overstrain of certain muscle groups, etc.

Finally, this is quite simple, if we follow a few rules: do not sit at the computer all day long, often air the room and do gymnastics. And then this smart machine will become our real friend.
