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 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 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 required 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 learn
Ordinary computer can remember only the data stored in the hard
disk. Now scientists have designed machines, that are capable of learning from
experience and remembering what they have learned. Such a machine is capable of
recognizing 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 loud-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 information 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 introduced for the senior forms at
schools. The pupils teach computers to investigate school problems. Contact
with the machine increases the interest in learning, makes them more serious
about studding new subject. School computers are used not only for studding
information science, but also examinations purposes. Young people who finish
the school must be trained to operate computers.
