The European Organization for Nuclear Research (French: Organisation européenne pour la recherche nucléaire), known as CERN (/ˈsɜːrn/; French pronunciation: [sɛʁn]; derived from the name "Conseil Européen pour la Recherche Nucléaire"; see History), is a European research organization that operates the largest particle physics laboratory in the world. Established in 1954, the organization is based in a northwest suburb of Geneva on the Franco–Swiss border, (46°14′3″N 6°3′19″E) and has 21 member states. Israel is the first (and currently only) non-European country granted full membership.
The term CERN is also used to refer to the laboratory, which in 2013 had 2,513 staff members, and hosted some 12,313 fellows, associates, apprentices as well as visiting scientists and engineers representing 608 universities and research facilities.
CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research – as a result, numerous experiments have been constructed at CERN as a result of international collaborations.
CERN is also the birthplace of the World Wide Web. The main site at Meyrin has a large computer facility containing powerful data processing facilities, primarily for experimental-data analysis; because of the need to make these facilities available to researchers elsewhere, it has historically been a major wide area networking hub.(Wikipedia)
