A wiki is software that allows users to collaboratively create, edit, link, and organize the content of a website, usually for reference material. Wikis are often used to create collaborative websites and to power community websites. These wiki websites are often also referred to as wikis; for example, Wikipedia is one of the best known wikis. Wikis are used in many businesses to provide affordable and effective Intranets and for Knowledge Management. Ward Cunningham, developer of the first wiki, WikiWikiWeb, originally described it as "the simplest online database that could possibly work".
Wiki Wiki (/wi?ki? wi?ki?/) is a reduplication of wiki, a Hawaiian word for "fast".
