What is a wiki? A wiki is a page or collection of Web pages designed to enable anyone who accesses it to contribute or modify content, using a simplified markup language

What is the purpose of a wiki? The purpose of Wiki is to help people understand things he or she knows nothing about. Users ask question while other users answer them to the best of their knowledge. The main feature that separates Wiki sites from other encyclopedia-type sites is that the users are able to make contributions to any article on a Wiki, such as adding or improving information, or to build up a community where anyone is free to edit.
