There is no single authority for the Internet. The WWW uses hypertext to interface with the Internet. These documents can be located anywhere on the Internet. The WWW is based on hypertext documents and is organized by keyword links. The WWW depends on server and client computers to access, display, and retrieve Web documents.
Documents are available from computers running server software.
Such computers are referred to as HTTP servers. A desktop computer runs client software and displays the contents of documents or uses other software to display the contents. The server and the client work together to provide access to the Internet.
