The set of instructions that are given to the computer for performing certain task is termed as software.My computer have become popular at present because of their various characteristics and so are used extensiveky almost in every filed. Acomputer help to reduce human memory burden of mechanical processing.Some of their distinctive characteristics as  follow:

Accuracy-     As  computers run under the control of programs, they are very accurate machines. It is human beings who make mistake by entering wrong commands into the computer. But if the command given to the computer are accurate, the result given vy the computer.
