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.
Computers in
medicine
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 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.
