Basic Client/Server WWW Model

Here is a diagram and description of the basic WWW client/server model which you must understand. The diagram is similar to Fig. P.1 (on page xviii) of your textbook (XHTML 1.0 Web Development Sourcebook by Ian S. Graham).

Diagram of client/server WWW model (description follows)

There are three main parts of the diagram: the client, the server, and the Internet. Other servers and clients are also pictured, to indicate that the client can connect to other servers and the server can be connected to by other clients.

Role of the Internet

The Internet is represented as a cloud (to indicate that it does not have a statically defined size or shape). Clients send requests to servers through the Internet, and servers send replies to clients through the Internet.

The client

The server
