Computers are-machines that accept incoming informations procedure them and bring forth outputs-depending on the users’ applications. Present clip. we are so much associated with these devices that without them we would non be able to populate the manner we do. They play a important function in everybody’s life. They bring a major socio-economic revolution non merely in India but besides in the whole universe itself. From pocket reckoners to personal computing machines ( Personal computer ) . nutrient processors and micro chips come ining through VCRS at place. their utilizations are manifolds. The computing machines are employed to help work forces in concern organisations. in infinite and other researches and in many other walks of life. The personal computing machine ( Personal computer ) is processing into the office where it is bettering productiveness by replacing paper plants. client services and occupation satisfactions for some. Why Computers are used widely?

The computing machines procedure information’s that come in all forms and sizes from any Fieldss so accurately that. some people may name these “Informatics”— The Science of Informal ion Processing. i. e. the methods of entering. manipulating and recovering information’s. It may be from a mathematical equation to a company’s work-force necessary to bring forth a paysheet or from meteoric section to calculate tomorrow’s conditions or from infinite research to project a new infinite trade. Whatever may be the instance. why computing machines are used widely? The following features that make the computing machines really popular for its many-sided utilizations may give the befitting answer.

( I ) Speed

First. the computing machines are regarded as high velocity reckoners. They can treat voluminous informations within a fraction of 2nd which no homo being could make before. If we want tomorrow’s prognosis today. meteorologists can utilize the computing machines for necessary computations and analyses. The units of velocity of a computing machine are the microsecond. the nano ( 10 ) -9 2nd and even the picot second.

( two ) Storage

As human encephalon can hive away the cognition in memory and can able to remember it. the Central Processing Unit ( CPU ) of a computing machine can make the same occupation without any failure. But the internal memory of CPU is merely big plenty to retain a certain sum of information. So. to hive away each and every information inside the computing machine. an Auxiliary or Secondary Storage Device is being attached outside the memory of the CPU.

( three ) Accuracy

The computing machines are much popular due to their high velocity along with systematically really high truth. Sometimes. the machinery may give mistakes. but due to increase in expeditiously error-detecting techniques. these seldom lead to false consequences. Most of the mistakes in computing machines are due to human himself.

( four ) Automation

Once a programme is in the computer’s memory. it will get down treating the input information’s ; therefore taking to mechanization. ( V ) Versatility The computing machines are various in nature. They can execute any undertaking given to them provided they are good programmed. ( six ) Diligence Bing a machine. a computing machine is really persevering in its responsibilities. It ne’er suffers from human weariness and fatigue or deficiency of concentration. It can execute 1000s after 1000s computations with precisely same truth and velocity as the first one without any remainder.
