A wiki is a website that uses wiki software, allowing the easy creation and editing of any number of interlinked Web pages, using a simplified markup language or a WYSIWYG text editor, within the browser.Wikis are often used to create collaborative websites, to power community websites, for personal note taking, in corporate intranets, and in knowledge management systems. Most wikis serve a specific purpose, and off topic material is promptly removed by the user community. Such is the case of the collaborative encyclopedia Wikipedia.In contrast, open purpose wikis accept all sorts of content without rigid rules as to how the content should be organized. Ward Cunningham, the developer of the first wiki software, WikiWikiWeb, originally described it as "the simplest online database that could possibly work." "Wiki" (pronounced [ˈwiki] or [ˈviki]) is a Hawaiian word for "fast"."Wiki" has been backronymed by some to "What I Know Is".
