A server is a piece of computer hardware or software (computer programme) that offers functionality to other programmes or devices known as "clients" in computing. The client-server model is the name given to this architecture. Servers can provide a variety of functions, sometimes referred to as "services," such as exchanging data or resources across several clients or conducting computation for a client. Multiple clients can be served by a single server, while a single client can use multiple servers.
