The home page resides on a server and is capable of holding information in various forms - text, graphics, video, and audio. Below is a picture of a home page viewed with a browser. When viewing a home page, you will notice that several words, lines, or graphics are underlined or somehow distinguished from other text and graphics in the document. These are referred to as hyperlinked information , or hypertext and hypermedia . If they are clicked on, will jump the viewer to another document or graphic. The server that provides the information called up by the hyperlink does not have to be "local" on the server, but can actually come from any location globally.

The services offered by ISPs can vary from merely offering a connection to full service, support, provision of on-site customer Internet servers, and "hosting content". Many ISPs will build a home page, convert files and graphics, forward leads, and update information for a one-time creation and monthly maintenance fee.

Intranet - In the same way that the world is networked and information shared between organizations, the same thing can be done using a LAN and WAN internally. Within a company, an internal structure of Web servers can make internal company information available between departments or even accessible to external staff via the Internet.

A "higher level" application protocol (e.g. HTTP, FTP, TELNET, etc.) can layer on top of the SSL Protocol transparently. The SSL protocol can negotiate an encryption algorithm and session key as well as authenticate a server before the application protocol transmits or receives its first byte of data. All of the application protocol data is transmitted encrypted, ensuring privacy.
