1. In general, a server is a computer program that provides services
to other computer programs on the same computer or on other computers.
2. The computer that a server program runs on is also frequently
referred to as a server (though it may contain a number of server
and client programs).
3. In the client/server programming model, a server is a program
that awaits and fulfills requests from client programs on the same
computer or on other computers. A given application in a computer
may function as a client with requests for services from other programs
and also as a server for requests from other programs.
Specific to the Web, a Web server
is the computer program (housed in a computer) that serves requested
HTML pages or files. A Web client is the requesting program associated
with the user. The Web browser in your computer is a client that requests
HTML files from Web servers.
