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.
