In 1970, less than 1% of the population could have intelligently defined what "computer software" meant. Today, most professionals and many members of the public at large feel that they understand software. But do they?
Software is (1) instructions (computer programs) that when carried out provide desired function and performance, (2) data structures that enable the programs to adequately manipulate information, and (3) documents that describe the operation and use of the programs. There is no question that other, more complete definitions could be offered. But we need more than a formal definition.
