Through the use of special software, they form a kind of network called, not surprisingly, a client-server network. Servers store information and process requests from clients. They then send the requested information to the clients. This information includes all kinds of data, including images, sounds, and text. Servers also send instructions to the client on how to display all this information.
Clients make request for information and then handle the chore of displaying that information.
When you are using a Web browser to navigate the Web, your browsing software is acting as a client. The World Wide Web is a distributed network. Any server on the Web can be accessed directly by any client. If a server on the World Wide Web malfunctions, it doesn't affect the performance of other servers. Users navigate the World Wide Web through the use of hypertext links.
