Wiki (English wiki) - a website whose content users can independently change using the tools provided by the site itself. Formatting text and inserting various objects into the text is done using the wiki markup. Based on these principles, Wikipedia and other projects of the Wikimedia Foundation
For the first time, the term "wiki" for describing the website was used in 1995 by Ward Cunningham, developer of the first WikiWikiWeb wiki system, the "Portland sample repository" program code created on March 25, 1995, which borrowed the word "Hawaiian" meaning "fast." Cunningham explained the choice of the engine's name in that he remembered an employee at Honolulu International Airport who advised him to use the wiki-wiki shuttle - a small bus shuttling between the airport terminals. Cunningham also planned to make the engine, allowing users to quickly edit and create articles. Cunningham originally described the wiki as "the simplest online database that can function." Later this word was invented by the English backronym "What I Know Is ..."
-Wiki offers all users to edit any page or create new pages on the wiki-site, using a regular web browser without any of its extensions. -Wiki supports links between different pages due to the almost intuitive creation of links to other pages and the display of whether there are data pages or not. -Wiki is not a carefully crafted site for casual visitors. On the contrary, Wiki seeks to attract visitors to the continuous process of creation and cooperation, which constantly changes the look of the site.
