Client/Server
Client/server describes the relationship between two computer programs in which one program, the
client, makes a service request from another program, the server, which fulfills the request.
A server is a computer program that provides services to other computer programs on one or many
computers. The client is the requesting program or user in a client/server relationship. For example,
the user of a Web browser is effectively making client requests for pages from servers all over the
Web. The browser itself is a client in its relationship with the computer that is getting and returning the
requested HTML file. The computer handling the request and sending back the HTML file is a server.
