In 1993, when commercial providers were first permitted to sell Internet connections to individuals, use of the network exploded. Several commercial online services, such as CompuServe, America OnLine, Prodigy and Genie, provide connections to members who pay a monthly fee. These internal webs use the same open standards, protocols and cross-platform client and server technology that are deployed across the World Wide Web. Every system connected to the Internet has a unique IP address. Most people use Domain Names and the resolution between Domain Names and IP addresses is handled by the network and the Domain Name Servers.
All Web sites are a collection of electronic pages.
Each page is a document formatted in HTML that contains text, images or media. The home page is typically a visitor's first point of entry and features a site index. Transmission Control Protocol works with IP to ensure that packets travel safely on the Internet. You can go straight to the site you want by typing the URL into the appropriate field on your browser. The Web allows browsers to easily navigate 3.2 million host computers in 70 countries.
