![]() Accuracy: Besides the efficiency, the computers are also very accurate. At present, a powerful computer can perform billions of operations in just one second. The speed of a computer is calculated in MHz (Megahertz), that is, one million instructions per second. A computer can perform a huge task in a few seconds that otherwise a normal human being may take days or even years to complete. Speed: The computer process data at an extremely fast rate, at millions or billions of instructions per second. Let us discuss some of the characteristics of computers, which make them an essential part of every emerging technology and such a desirable tool in human development. Today, much of the world's infrastructure runs on computers and it has profoundly changed our lives, mostly for the better. Explain the Character istics of Computers? The human race developed computers so that it could perform intricate operations, such as calculation and data processing, or simply for entertainment. In simple terms, computer is an electronic device which accepts the input (Data) from the user, processes it and produces the output (Information). A computer is an electronic machine, devised for performing calculations and controlling operations that can be expressed either in logical or numerical terms.The term computer is derived from a latin word 'computare' meaning 'to compute' (to calculate). Computers are termed as 'Man of the Year' in a magazine recently.
