'''occam''' is a [[programming language]] which is [[Concurrent computing|concurrent]] and builds on the [[communicating sequential processes]] (CSP) process algebra,<ref name="oc21refman">{{cite book |author=<!--Must be person--> |author-link=Inmos |url=http://www.wotug.org/occam/documentation/oc21refman.pdf |title=occam 2.1 Reference Manual |publisher=SGS-Thomson Microelectronics Ltd |date=1995-05-12}} Inmos document 72 occ 45 03</ref> and shares many of its features. It is named after philosopher [[William of Ockham]] after whom [[Occam's razor]] is named.

Occam is an [[Imperative programming|imperative]] [[Procedural programming|procedural]] language (such as [[Pascal (programming language)|Pascal]]). It was developed by [[David May (computer scientist)|David May]] and others at [[Inmos]] (trademark INMOS), advised by [[Tony Hoare]], as the native programming language for their [[transputer]] [[microprocessor]]s, but implementations for other platforms are available. The most widely known version is occam 2; its programming manual was written by Steven Ericsson-Zenith and others at [[Inmos]].
