acronym - Computer Definition
A pronounceable word formed of the initial letters or other parts of several words.An acronym generally comprises all upper case letters. SONET, for example, is the acronym for Synchronous Optical NETwork, a North American standard for fiber optic transmission systems. SONET became internationalized as SDH, an unpronounceable initialism for Synchronous Digital Hierarchy. Acronyms occasionally comprise all lower case letters. For example, bit is the acronym for binary digit, which is the basic unit of information in a binary numbering system. Bit also is a word unto itself, and with multiple meanings, including a small piece of something. Acronyms sometimes comprise both upper case and lower case letters. Sesame, for example, is the acronym for Secure European Systems for Applications in a Multivendor Environment. See also abbreviation, anacronym, backronym, contraction, initialism, and portmanteau.
A word typically made up of the first letters of two or more words; for example, BASIC stands for "Beginners All purpose Symbolic Instruction Code." Letters within a word are also used; for example, XML means "eXtensible Markup Language." Technically, if only first letters are used, the term is an "initialism," but this distinction is not widely made. For an excellent acronym resource, visit www.acronymfinder.com. See backronym.

A word formed by combining the beginning letters of a name or phrase, as in WASP for white Anglo-Saxon Protestant, or by combining the initial syllables of a series of words, as in radar, which stands for radio detecting and ranging.
