Using the Internet
What Is the Internet?
The Internet is a shared network of PCs that
transmit data and make the electronic exchange
of information possible. Documents are stored on
servers (specialized PCs) on the Internet.
Many of these documents are Web pages, part
of the interlinked World Wide Web. They use
Hypertext Transfer Protocol (HTTP) to deliver
information in a format readable by your Web
browser. Millions of documents, pictures, software
files, and entertainment files are available on the
World Wide Web.
What Is a Hyperlink?
Imagine you’re reading a newspaper. On page 1,
you may read something like “For more details, see
page 3, column 2.”
A hyperlink on a Web page works the same way,
except that the jump to related information occurs
electronically, with a click of the mouse to launch
the hyperlink. You can move instantly from page to
page, Web site to Web site. Linking files together is
what gives the Web its name, weaving and
connecting idea to idea, all over the world.
