software instructions executed by a computer, as opposed to the physical device on which they run (the "{hardware}"). The term was coined by the eminent statistician, {John Tukey}. Programs stored on {non-volatile storage} built from {integrated circuits} (e.g. {ROM} or {PROM}) are usually called {firmware}. Software can be split into two main types - {system software} and application software or {application programs}. System software is any software required to support the production or execution of application programs but which is not specific to any particular application. Examples of system software would include the {operating system}, {compilers}, editors and sorting programs. Examples of application programs would include an accounts package or a {CAD} program. Other broad classes of application software include {real-time} software, {business software}, scientific and engineering software, {embedded software}, personal computer software and {artificial intelligence} software. Software includes both {source code} written by humans and executable {machine code} produced by {assemblers} or {compilers}. It does not usually include the data processed by programs unless this is in a format such as {multimedia} which depends on the use of computers for its presentation. This distinction becomes unclear in cases such as {spread sheets} which can contain both instructions (formulae and {macros}) and data. There are also various intermediate compiled or {semi-compiled}, forms of software such as {library} files and {byte-code}. Some claim that {documentation} (both paper and electronic) is also software. Others go further and define software to be programs plus documentation though this does not correspond with common usage. The noun "program" describes a single, complete and more-or-less self-contained list of instructions, often stored in a single {file}, whereas "code" and "software" are uncountable nouns describing some number of instructions which may constitute one or more programs or part thereof. Most programs, however, rely heavily on various kinds of {operating system} software for their execution. The nounds "code" and "software" both refer to the same thing but "code" tends to suggest an interest in the implementation details whereas "software" is more of a user's term. (2002-07-21) | |
