Differences between Wikipedia, Wikimedia, MediaWiki, and wiki/ko

MediaWiki(이하 미디어위키), Wikimedia(이하 위키미디어), Wikipedia(이하 위키피디아), wiki(이하 위키) 가 혼동되십니까?

위키
위키 는 어떤 사용자라도 편집할 수 있는 협력가능한 웹사이트의 종류를 일컫는 일반적인 용어로써, 고유명사가 아닙니다.
 * 형용사로써의 위키, 혹은 위키적인 방식, 위키적이지 않은 과 같은 말들은 공동체내에서 지향하는 철학을 설명할때 쓰입니다. (예를 들면, "그건 별로 위키적인 방식이 아니야")
 * Wiki (W가 대문자) 는 최초의 위키였던 WikiWikiWeb 혹은 Portland Pattern Repository 로 알려진 사이트를 말합니다.
 * wiki software and wiki engine are terms referring to pieces of software that power wiki-based websites. There are many different types of wiki software; some very simple, others enhanced with specific advanced features. See also: Wikipedia's entry on "wiki software" or the Portland Pattern Repository's "canonical" list of wiki engines.

For a more complete description, see Wikipedia's entry on "wiki".

Wikimedia
Wikimedia is the collective name for a group of inter-related projects, including Wikipedia, Wiktionary, Wikisource, Wikibooks, and others, which aim to use the collaborative power of the Internet, and the wiki concept, to create and share free knowledge of all kinds. Like "Wikipedia", "Wikimedia" is a trademark, and should not be used for projects which are not officially affiliated. Wikimedia is also used as a shortened form of The Wikimedia Foundation.


 * The Wikimedia Foundation is the non-profit organization which funds and manages these projects. For more information, see the Foundation's homepage
 * The term Wikimedia servers is often used, referring to the computer hardware on which all Wikimedia projects are hosted. The servers are run by employees of the Wikimedia Foundation, many of whom also work on the MediaWiki software (see below). The Wikimedia servers are not available for hosting projects not run by the Wikimedia Foundation. See also: Wikimedia servers.
 * The Wikimedia Meta-Wiki, commonly referred to as Meta, is the wiki used to discuss issues which affect all Wikimedia projects. See also: About.
 * Meta should not be confused with MetaWiki, a search engine that is not part of the Wikimedia group of projects.
 * Wikimedia Deutschland, Wikimedia Russia etc. are not part of Wikimedia Foundation, but usually are friends of it.
