Wiki
From Computing and Software Wiki
A wiki is a medium which can be edited by anyone with access to it, and provides an easy method for linking from one page to another. Wikis are typically collaborative websites , though there are now also single-user offline implementations. Ward Cunningham, developer of the first wiki, WikiWikiWeb, originally described it as "the simplest online database that could possibly work". One of the best-known wikis is Wikipedia[1].
