- "A wiki is a type of website that allows users to easily add, remove, or otherwise edit and change some available content, sometimes without the need for registration. This ease of interaction and operation makes a wiki an effective tool for collaborative authoring. The term wiki can also refer to the collaborative software itself (wiki engine) that facilitates the operation of such a website (see wiki software), or to certain specific wiki sites, including the computer science site (and original wiki), WikiWikiWeb, and the online encyclopedias such as Wikipedia. The first wiki, WikiWikiWeb, is named after the "Wiki Wiki" line of Chance RT-52 buses in Honolulu International Airport, Hawaii. It was created in 1994 and installed on the web in 1995 by Ward Cunningham, who also created the Portland Pattern Repository. "Wiki-wiki" means "hurry quick" in Hawaiian. It also refers to a type of fish native to the islands."
