Computers
A computer was invented in
the 20th century. The first computers were very big because there were
thousands of tubes in them. But they were not used for a long time, as
scientists invented first transistors instead of tubes and then micro-diagrams.
Computers became smaller and now they can stand on the writing desk in a flat,
but do calculations much faster. Now a computer can do one millions sums in one
second. No man can do that.
Today computers are used widely because they
are more efficient than human beings.
They can calculate
the orbits of sputniks and spaceships, control machines in factories, work out
tomorrow’s weather, reserve seats on plane, pay wages, play chess, write poetry
or compose music. Computers can also make a translation from one language into
another.
They are a great help to a student, a
doctor, a teacher, a librarian, a composer, a designer, an agronomist.
How much information computer can store! They
are ready to help people at any moment. In fact, they can do many of the things
we do, but faster and better. Today computers control nearly everything we do
in the world. They serve people in their daily lives and work.
