SOFTWARE

                 A computer can neither think nor work on its own. It has to be provided with a set of pre-defined instructions
                 which are written in a computer language. Such sets of instructions are known as ‘Programs’. A set of organized
                 programs meant for a specific purpose is known as  Software . Software is an intangible part of a computer.

                 Software can be broadly classified as:
