International Organization for Standardization
<standard, body> (ISO) A voluntary, nontreaty organisation founded in 1946, responsible for creating international standards in many areas, including computers and communications.
Its members are the national standards organisations of 89 countries, including the American National Standards Institute.
ISO produced the OSI seven layer model for network architecture.
The term "ISO" is not actually an acronym for anything.
It is a pun on the Greek prefix "iso-", meaning "same".
Some ISO documents say ISO is not an acronym even though it is an anagram of the initials of the organisation's name.
