What is a Computer?
Nowadays, in most modern societies, almost
everybody has idea about what a computer is.
We depend on computers in every aspect of our
lives whether we know how to use one or not.
But does everyone really know how a computer
works inside?
A computer is an electronic machine which
processes data and provides the results of the
processing as information. There are three basic
steps in the computing process. The first one is
input, which consists of feeding data into the
computer’s memory. Then comes the
processing: the program is run and the
computer processes the data by performing a
set of instructions. The third and final step is the
output furnished by the computer, which allows
the user to see the results either in printed form
or on the screen.
The world of computers has created a
specific language of its own. English words such
as software and hardware are used worldwide
and have been borrowed by many different
languages. Software is information in the form
of data and programs, and hardware refers to
the electronic and mechanical parts that make
up a computer system.
Despite the constant presence of computers
in most modern societies, it is a great mistake to
believe that everybody in the world is computerliterate, i.e., is familiar with computers and
knows how to use them properly. In some
contemporary societies, many people still have no idea about the existence of computers, and
even in the so-called developed countries, there
are lots of people who do not know or do not
care about what a computer is.
