The Computer Or The Use of Computer
Introduction: Science has raised human
civilization up to the highest peak. So long we are enjoying the benefits of
cinema, radio, television, telegraph, telephone, x-ray and so on. At present,
we are enjoying the benefit of another wonderful invention science. It is the computer
that has come forward to work as a substitute for the human brain.
What is it: A computer is an ultra-modern
electronic device for storing and analyzing information fed into it? It has no
capacity to do anything by itself. It works on the basis of commands given by
the operator.
History: The computer was not invented
overnight. It took a long time and hard labour to invent the computer. Charles Babez,
a British professor of Mathematics first thought of formulas that could help the human brain. His attempts were not crowned with success but he initiated the
research leading to the invention of the computer. Finally, Mr. Howard Akin, an
American scientist invented such a machine in 1937 that could solve difficult
mathematical problems. So it is Howard Akin who is credited for the
invention of the computer. After seven years electric computer was used at Harvard
University.
Components and function: A computer
consists of five major components. They are the input unit, the output unit, the
memory unit, the control unit, and the arithmetic unit. A computer performs the
following three functions:
- It receives data.
- It processes data by various computations.
- It emits data.
Variety of uses: The computer renders a
great variety of services to mankind like Aladdin’s magic lamp. It serves man
in so many ways that cannot be counted. It translates poems or any part of
literature. A farmer sitting in his house can complete the whole process of
cultivation from ploughing of the lands to the thrashing of corn. Trains and
planes are run by computer. Examination results are correctly given by the
computer. The computer is used to extract minerals. The computer is used to
diagnose diseases. A newer process of operation has been invented by computer
as an alternative to surgery. At present business, trade, and commerce cannot be
thought without a computer. It is used to prepare documents, make lists of goods,
store information prepare budgets, etc It is the computer that helps man to
conquer space. Time is not far off when every brain work will be done by the
computer.
Demerits: Everything has its dark
sides. The computer has its own demerits. It causes diseases like respiratory
stress injury and harms the eyesight of the operators. School-going children
remain occupied with playing computer games instead of learning their lessons.
Conclusion: The computer is the greatest
contribution of science so far made. It renders the greatest service to
humanity by substituting the human brain by saving time and preventing its
misuse.
