Ward Cunningham, inventor of the wiki
A wiki (Listeni/ˈwɪkiː/ WIK-ee) is a website which allows its users to add, modify, or delete its content via a web browser usually using a simplified markup language or a rich-text editor. Wikis are powered by wiki software. Most are created collaboratively.
Wikis serve many different purposes, such as knowledge management and notetaking. Wikis can be community websites and intranets, for example. Some permit control over different functions (levels of access). For example, editing rights may permit changing, adding or removing material. Others may permit access without enforcing access control. Other rules may also be imposed to organize content.
Ward Cunningham, the developer of the first wiki software, WikiWikiWeb, originally described it as "the simplest online database that could possibly work." "Wiki" (pronounced [ˈwiti] or [ˈviti]) is a Hawaiian word meaning "fast" or "quick".
