When Charles Babbage, a professor of Mathematics at Cambridge university, invented the first calculating machine in 1812 he couldn't even imagine the consequences of this discovery. Nearly everything we do in the world is assisted or even controlled by computers, the complicated descendants of his simple machine. Computers are used more and more often in the world today, for the simple reason that they are far more efficient than human beings. They have much better memory 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 even 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 in medicine
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 acquired 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 symptoms of various diseases and of their treatment is stored. Doctors feed data on symptoms in the computer and get the necessary information on correct diagnostics and treatment.
Computers that can be taught
Ordinary computer can use only the data stored in the hard disk. Now scientists have designed machines, that are capable of learning from their experience and remembering what they have learned. Such a machine is capable of recognizing objects without human help or control. But of course, they can make many mistakes.
Computers at the school
Information science with the ideas and message of processing and storing information is of great importance today. That's why computer technology must be taught in secondary school. The new subject "basic information science", and "computing machines" was introduced for the senior pupils at schools. Contact with the machine increases the interest in learning, makes them more serious about studying new subject. School computers are used not only to study information science, but also for examination purposes. Young people who finish the school must be trained to operate computers.
