Computers

 

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.
