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.

Wikipedia is a free content online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and the use of the wiki-based editing system MediaWiki. Wikipedia is the largest and most-read reference work in history.

An easy way of switching from the standard English entry to the simplified one is to swap the '. en' prefix to 'simple' in the URL.

The latest database dump of the source of all pages, current versions only, heavily compressed, is 35.4 GB. The media files local to Wikipedia are 142.5 GB (uncompressed). Wikipedia's media files are usually hosted on Wikimedia Commons, which has 359.52 TB of media (uncompressed). Not every file is used on Wikipedia.
