Wiki

A wiki (IPA: [ˈwɪ.kiː] or [ˈwiː.kiː] ^[1]) is a website that allows visitors to add, remove, and otherwise edit and change content, typically without the need for registration. It also allows for linking among any number of pages. This ease of interaction and operation makes a wiki an effective tool for mass collaborative authoring. The term wiki also can refer to the collaborative software itself (wiki engine) that facilitates the operation of such a site, or to certain specific wiki sites, including the computer science site (the original wiki) WikiWikiWeb and online encyclopedias such as Wikipedia.
