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.
