What is Server?

A server is a computer that handles requests for data, e-mail, file transfers, and other network services from other computers (i.e., clients).The term can refer to a particular piece of software, such as a WWW server, or to the machine on which the software is running, e.g. Mail servers.

A single server machine can (and often does) have several different server software packages running on it, thus providing many different servers to clients on the network.

Dedicated servers are very common when it comes to Web hosting.
