What is a wiki? definition

A wiki is a page or collection of Web pages designed to enable anyone who accesses it to contribute or modify content, using a simplified markup language.[1[[http://en.wikipedia.org/wiki/Wiki#cite_note-0|]]][2[[http://en.wikipedia.org/wiki/Wiki#cite_note-Britannica-1|]]] Wikis are often used to create collaborative websites and to power community websites. The collaborative encyclopedia Wikipedia is one of the best-known wikis.[2[[http://en.wikipedia.org/wiki/Wiki#cite_note-Britannica-1|]]] Wikis are used in business to provide intranet and Knowledge Management systems. Ward Cunningham, the developer of the first wiki software, WikiWikiWeb, originally described it as "the simplest online database that could possibly work".[3[[http://en.wikipedia.org/wiki/Wiki#cite_note-2|]]]
"Wiki" (/wiːkiː/) is a Hawaiian word for "fast"[4[[http://en.wikipedia.org/wiki/Wiki#cite_note-3|]]]. "Wiki Wiki" is a reduplication. "Wiki" can be expanded as "What I Know Is," but this is a backronym.[5[[http://en.wikipedia.org/wiki/Wiki#cite_note-economist-wiki-4|]]]
