What is a wiki?
A wiki (i// wik-ee) is a website whose users can add, modify, or delete its content via a web browser using a simplified markup languageor a rich-text editor. Wikis are typically powered by wiki software and are often created collaboratively by multiple users. Examples include community websites, corporate intranets, knowledge management systems, and notetaking.
According to Leuf & Cunningham (2001), creators of the original wiki concept, a wiki is a freely expandable collection of interlinked webpages, a hypertext system for storing and modifying information - a database, where each page is easily edited by any user with a forms-capable web browser client.
Wikis may serve many different purposes. Some permit control over different functions (levels of access). For example, editing rights may permit changing, adding or removing material. Others may permit access without enforcing access control. Other rules may also be imposed for organizing content.
