Surfing the Internet
The Internet is a worldwide network of computer networks. Computer networks
are two or more computers linked or connected together by cables or phone lines.
These computers are linked together to provide seemingly endless amounts of
information for research, education, commerce, and entertainment purposes. This
information is stored on computers called Web servers. Web servers are set up
exclusively for Internet users to access this information.
The graphic below illustrates how a Web site stored on a Web server in North
America can be viewed all around the world.
The Internet
When you “surf” the Internet, you are accessing these millions of computers and
reviewing the information that they have stored on their Web servers.
Internet Addresses (URLs)
Surfing the Internet is made possible by the addresses assigned to these linked
computers. The Web address (also called the Uniform Resource Locator, or URL)
allows other computers to view the information as Web pages. For example, the
Compaq Web site address is www.compaq.com. When you access this address, the
Compaq Web site and all associated Web pages can be viewed on your
Internet PC.
