A wiki is a site that is designed for groups of people to quickly capture and share ideas by creating simple pages and linking them together. Your organization can use a wiki for a variety of uses. On a large scale, you can share large volumes of information in an Enterprise wiki.

Because Wikipedia cannot be considered a reliable source, the use of Wikipedia is not accepted in many schools and universities in writing a formal paper, and some educational institutions have banned it as a primary source while others have limited its use to only a pointer to external sources.

Simply put, there are two types of wikis: public, like Wikipedia, and private, otherwise known as “internal wikis.”
