Computer software is a collection of computer programs and related data that provides the instructions for telling a computer what to do and how to do it. Software refers to one or more computer programs and data held in the storage of the computer. In other words, software is a set of programs, procedures, algorithms and its documentation concerned with the operation of a data processing system. The term was coined to contrast to the old term hardware (meaning physical devices). In contrast to hardware, software ‘;cannot be touched’. Software is also sometimes used in a more narrow sense, meaning application software only. Sometimes the term includes data that has not traditionally been associated with computers, such as film, tapes, and records. This publication titled, ‘;Computer Software’ provides readers with an introduction to computer software and related subjects.
