Domain Name

In short, a domain name is nothing more than an alias for a numeric Web address. Each Web site on the Internet has a numeric address that functions like coordinates on a map. Instead of pointing to a geographic location on Earth, these numeric addresses, called IP addresses, point to a location on the Internet. Computers have no problems with locating and remembering numeric addresses. In contrast, many people have trouble remembering long, complicated sequences of numbers. So, to make navigating the Internet easier, the domain name system was invented. This system allows people to use easy-to-remember names for Web sites instead of numeric sequences.

HTML files are meant to be viewed using a browser, such as Netscape or Internet Explorer.
