NOTE: The : HTTP:// in an address means: (Hypertext Transfer Protocol)
Companies are not the only people who have their own servers. (remember, the server is the expensive, high capacity computer which stores the web pages) You may see addresses like:
www.whitehouse.gov (The Whitehouse)
www.wwf.org (the World Wildlife Fund).
There are several "extensions" which are used as the last three letters of an address. The address extension, like filename extensions, tells us something about the people using them. The common extensions and meanings include:
.gov = government
.mil = military
.org = non-profit organizations
.net = networks, or Internet Service Providers.
.com = companies or commercial
.edu = educational
Finally, sometimes you will see a 2 letter code after the extension, such as: www.somecompany.com.au.
The .au indicates the company is located someplace other than the United States. In this case it is in Australia. Each country is assigned its own 2 letter code.
Each Server can have many Domains. A Domain address makes your address look like you have your own server. In effect you do, although the domain may actually reside on the same physical server with many other domains
