Lately computers have filled our life. Now they are almost in each family. We have got used to them and we do not imagine our leisure without this miracle-machine.

With the help of computers the Internet has entered into our life. It became an integral part of a life of each person. Now people cannot live a day without checking of mail and visiting their favourite sites. The Internet is not only the assistant in daily work, it is also the other world in which there are mail boxes, libraries, photo galleries, games, shops. By means of the Internet people can travel to different cities, visit tourist places, communicate with people.

Recently many people ask a question: » Is the Internet harmful or useful? «. I think, that on this question there is no certain answer. In fact on the one hand the Internet is a very good and useful thing. And on the other hand it has many negative functions: dependence, the waste of time, money, health.

Certainly, the Internet can be the excellent assistant in information search. But if we spend a lot of time on the Internet we`ll have some problems. We lose a touch with the real world, get in a full dependence on a computer. I think, that it is important to learn to distinguish a side between a real life and a life on the Internet. For that it is necessary to understand, what is really important on the Internet and what is not . And then the Internet will be not the terrible enemy, but the indispensable assistant.

   When Charles Babbage, a professor of Mathematics at Cambridge university, invented the first calculating machine in 1812 he couldn’t imagine the situation we find ourselves in today. Nearly everything we do in the world is helped, or even controlled by computers, the complicated descedants of his simple machine.

   Computers are used more and more often in the world today, for the simple reason that they are far more efficent than human beings. They have much better memories and they can store much information. No man alive can do 500000 sums in one second, but a computer can. In fact, computers can do many of the things we do, but faster and better. They can predict weather, and ever play chess, write poetry or compose music.

   Just as television has extended human sight across the barriers of time and distance, so the computers extend the power of the human mind across the existing barriers.

   Computers are one of great importance in modern hospital. The chief use of computers is the storing and sorting the medical knowledge which has been equired in the last 50 years. No doctor can possible keep up with all discoveries. The only solution of the problem is store medical knowledge in a computer. Today there are medical computer centers were all existing knowledge of simpthoms of various dessieses and of their treatment is stored. Doctors feed data on simpthoms in the computer and get the nessesary information on correct diagnostics and treatment.

   Ordinary computer can remember only the data stored in the hard disk. Now scientists have desighned machines, that are capable of learning from experience and remembering what they have learned. Such a machine is capable of recognising objects without human help or control. Of course, they made many mistakes.

   There is another similar machine which can look at letter alphabet a simple words and they "say" thought a loudes speaker what it has seen. The machine has as certain learning power.

   Information science with the ideas and message of processing and storing informations is of great importance today. That’s why computer technology must be tought in secondary schools. Contact with the machine increases the interest in learning, makes them more serious about studing new subject. School computers are used not only for studing information science, but also examinations purposes. Young people who finish the school must be trained to operate computers.
