Computer software (or simply software) refers to one or more computer programs and data held in the storage of a computer for some purpose. Program software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another piece of software. Data software exists solely for its eventual use by other program software.

The term software was first used in this sense by John W. Tukey in 1957; colloquially, the term is often used to mean application software. In computer science and software engineering, computer software is all information processed by computer system, programA computer program (often simply called a program is an example of computer software that prescribes the actions (" computations") that are to be carried out by a computer. Most programs consist of a loadable set of instructions which determines how the cs and data.

Computer software is often contrasted with computer hardware, which is the physical substrate on which software exists.

For other uses of the word software see Software (disambiguation)Software can refer to any of the following: Computer software In retailing, software refers to clothing. Downloading some software is a euphemism for defecating..

1 System and application software

Computer science divides software into two big classes: system softwareSystem software is a generic term referring to any computer software whose purpose is to help run the computer system. Most of it responsible directly for controlling, integrating, and managing the individual hardware components of a computer system. and application software. All other subclasses belong to these two classes.
System softwareSystem software is a generic term referring to any computer software whose purpose is to help run the computer system. Most of it responsible directly for controlling, integrating, and managing the individual hardware components of a computer system. helps run the computer hardware and computer system. It includes operating systems, device drivers, programming tools, servers, windowing systems, utilities and more.
Application software allows a user to accomplish one or more specific tasks. Typical applications include office suites, business software, databases and video games. Most of application software has GUIs.
