Wiki
A wiki ( WIK-ee) is a form of hypertext publication on the internet which is collaboratively edited and managed by its audience directly through a web browser. A typical wiki contains multiple pages that can either be edited by the public or any organization. The name derives from the first user-editable website called WikiWikiWeb – wiki being a Hawaiian word meaning 'quick' (pronounced [ˈviti]).
Wikis are powered by wiki software, also known as wiki engines. Being a form of content management system, these differ from other web-based systems such as blog software or static site generators in that the content is created without any defined owner or leader.
