A wiki is a hypertext environment (usually a Web site) for collecting and structuring written information. Characterized by the following features:

• A lot of authors. Some wikis can be edited by all visitors.
• The ability to repeatedly edit the text through the wiki itself (the website), without the use of special tools on the editor's side.
• Manifest changes immediately after they are made.
• Separation of information into pages where each has its own name.
