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.

The use of computers

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

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.

Computers that can be learn

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.

Computers at the school

Information science with the ideas and message of processing and storing

informations is of great importance today. That\'s why computer technology

must be told in secondary school. The new subject “basic information

science”, and “computing machine” was intreduste for the siner forms at

schools. The pupils teach computers to anlestigate school problems.

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.
