The computing definition is inaccurate. A semaphore is non-binary (that is, it is not a bit), and while it can be used to function as a mutual exclusion lock as described on this page, it can and does serve other purposes as well. I'd change it myself, but don't really know how to word it well ... --198.107.20.174 01:51, 9 April 2006 (UTC)
