What can a Computer do?
A computer is an electronic device. It consists of various sub-systems, like
memory, micro-processor, input system and output system. All these sub-
systems work together to make it an integrated system. It is an extremely powerful
device, which is apt to have an important effect on the systems of data processing,
mapping and analysis. A computer is a fast and a versatile machine that can
perform simple arithmetic operations, such as, addition, subtraction,
multiplication and division, and can also solve complex mathematical, formulae.
It also performs simple logical operations, distinguishing zero from non-zero
and plus from minus and discharge the results. In short, a computer is a data
processor that can perform substantial computation, including numerous
arithmetic or logical operations, without intervention by a human operator during
the run.
