Created page with a fair amount of info. More body needed, and other non-existent pages linked to are also needed at some point.

A '''Server''' is a special kind of computer designed solely to supply (serve) information to clients. They use the [[client-server model]] to do this.

==Kinds of Servers==
*[[Web server]]s - Offer webpages and webpage-related files (a website) usually using the [[Hyper-Text Transfer Protocol]] or [[Hyper-Text Transfer Protocol Secure]]
*[[File server]]s - Offer files not directly related to a specific website (there will sometimes be a comparatively small website on the same server to aid in distribution) using the [[Hyper-Text Transfer Protocol]]
*[[FTP server]]s - A kind of file server which uses the [[File-Transfer Protocol]] rather than the more common [[Hyper-Text Transfer Protocol]] of the previous type
*[[Proxy server]]s - Go-between servers which web traffic may be tunneled to for privacy or restriction avoidance
*[[Game server]]s - Enable clients to play games online with other clients<ref>http://compnetworking.about.com/od/basicnetworkingconcepts/g/network_servers.htm</ref>

==Clusters==
Servers are often grouped into server clusters. These clusters usually consist of at least two server computers which could operate independently. They are generally made to improve performance of a website or other virtual server--this is especially important for popular websites.<ref>http://compnetworking.about.com/od/basicnetworkingconcepts/g/network_servers.htm</ref> For example, each server computer may support up to 1,000 clients, but if a website receives more than this at a time, it will be overloaded. With a cluster, however, clients will be distributed throughout the available servers to avoid overload.<ref>https://technet.microsoft.com/en-us/library/cc785197%28v=ws.10%29.aspx</ref>
Many large websites and services use clusters, including Amazon.{{citation needed}}
