Software consists of computer programs, data structures, and documentation that provide desired features and functions. Software is engineered rather than manufactured, does not wear out over time, and is often custom-built despite a trend toward component-based construction. Software is a product that delivers computing potential through transforming, managing, and transmitting information while controlling other programs, enabling communications, and aiding in further software development.

Introduction to software
- 1. 1 What is Software Software is: (1) instructions (computer programs) that when executed provide desired features, function, and performance; (2) data structures that enable the programs to adequately manipulate information and (3) documentation that describes the operation and use of the programs. Introduction
- 2. 2 Characteristics of S/W • Software is developed or engineered, it is not manufactured in the classical sense. • Software doesn't "wear out." • Although the industry is moving toward component- based construction, most software continues to be custom-built.
- 4. Nature of Software Software is a Product Software is a vehicle for delivering a product • Transforms information- produces, manages, acquires, modifies, displays or transmits information • Delivers computing potential of hardware and networks • Controls other programs (operating system) • Effects communications (networking software) • Helps build other software (software tools & environments)
