Editing Client–server model (section)

===Client-host and server-host===
''Client-host'' and ''server-host'' have subtly different meanings than ''client'' and ''server''. A host is any computer connected to a network. Whereas the words ''server'' and ''client'' may refer either to a computer or to a computer program, ''server-host'' and ''client-host'' always refer to computers. The host is a versatile, multifunction computer; ''clients'' and ''servers'' are just programs that run on a host. In the client–server model, a server is more likely to be devoted to the task of serving.

An early use of the word ''client'' occurs in "Separating Data from Function in a Distributed File System", a 1978 paper by Xerox PARC computer scientists Howard Sturgis, James Mitchell, and Jay Israel. The authors are careful to define the term for readers, and explain that they use it to distinguish between the user and the user's network node (the client).<ref>{{Cite web| title=Separating Data from Function in a Distributed File System |last1 = Sturgis |first1 = Howard E. |last2 = Mitchell |first2 = James George |last3 = Israel | first3 = Jay E. |publisher=[[PARC (company)|Xerox PARC]] |url=http://ip.com/IPCOM/000128883 |year = 1978}}</ref> By 1992, the word ''server'' had entered into general parlance.<ref>{{OEtymD|server|accessdate=30 November 2013}}</ref><ref>{{cite web |url=https://getinfo.de/app/Separating-data-from-function-in-a-distributed/id/TIBKAT%3A509976956 |title=Separating data from function in a distributed file system |author=<!--Staff writer(s); no by-line.--> |website=[[GetInfo]] |publisher=[[German National Library of Science and Technology]] |access-date=29 November 2013 |archive-url=https://web.archive.org/web/20131202233729/https://getinfo.de/app/Separating-data-from-function-in-a-distributed/id/TIBKAT%3A509976956 |archive-date=2 December 2013 |url-status=dead }}</ref>
