wiki [Hawaiian, wikiwiki = fast], a website designed to permit the development of information resources by creating hyperlinked webpages using software that accessed through a web browser. First devised and named by Ward Cunningham in 1995 when he created the WikiWikiWeb to record and share programming techniques, wikis generally use relatively simply markup (encoding for formatting) to enable the easy creation of content, and as a result typically produce relatively straightfoward webpage layouts. Wikis are usually collaborative, unlike most blogs, and may be found in a wide range of settings. They may, for example, be on the Internet and permit content creation and revision by any person, or may be on a company's internal network (intranet) and be accessible only to specific employees. The best known wiki is the online encyclopedia Wikipedia. See also hypertext.
