Wikimedia Foundation
powered by MediaWiki : a Wiki or
wiki is a website (or other hypertext document collection) that allows
users to add content, as on an Internet forum, but also allows anyone to
edit the content. "Wiki" also refers to the collaborative software used
to create such a website. Wiki (with an upper case 'W') and WikiWikiWeb
are both used to specifically refer to the Portland Pattern Repository,
the first-ever wiki. This usage's proponents suggest a lower-case 'w' for
wikis in general. The name was based on the Hawaiian term wiki wiki, meaning
"quick" or "super-fast". Sometimes wikiwiki or WikiWiki are used instead
of wiki.
Wikipedia - The Free Encyclopedia,
one of the 200
most visited websites in the world : inspired by the power of the web,
Jimmy Wales co-founded the online encyclopaedia Wikipedia in early 2001.
The reference tool takes advantage of Wiki technology, which allows Internet
users to modify websites other than their own. As a result, they can change
content and add entire new pages to the collaborative, multilingual project.
