A Wiki is a system for building and maintaining collections of web pages. It helps people create simple pages about various topics that they can link together. Wiki users can add or change pages in their web browsers without worrying about how or where the content is stored. Wikis, therefore, are collaborative, often used by online communities with similar interests. Wikis use a simple syntax to format text and create links, so users don't have to know HTML to create online content. If someone makes a mistake when creating wiki content, they can revert to an earlier version of the document.
