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.
