Internet
The Internet, sometimes called the Net, is a vast
group of interconnected computer networks that spans the globe. It has
many features, but is generally a way to communicate, use information
tools, and find boundless amounts of information from an unlimited number
of sources.
The Internet makes possible a number of online functions
such as e-mail, a way of sending messages electronically from one computer
user to another; chat rooms, which are places online where you
can communicate with others instantaneously using your keyboard; and
discussion groups, places where you can read and post information
about particular topics.
There is unlimited information on the Internet,
but it can be like a big library without a card catalogue to help find
the books you might be looking for. Search engines exist to help
with this. With a search engine you can sort through vast amounts of
online information to pinpoint the material you want. Search engines
work by matching words you enter into the computer with the same words
found in various information sites on the Internet.
World Wide Web
What has helped the Internet become more popular
is the development of the World Wide Web. The World Wide Web
(WWW or the Web) is a network of sites on the Internet which have words,
sounds, and pictures. It is its visual quality that distinguishes the
Web from the rest of the Internet. Here, commercial companies, nonprofit
organizations, the government, and individuals supply lots of information
on just about any subject imaginable. In fact, many organizations and
commercial outlets are creating "content" or information aimed directly
at kids of all ages, and kids are spending a lot of time on the Web.
A necessary tool for exploring the Web is a browser,
a program that lets you view what's on the Web. Examples of popular
browsers are Netscape Navigator and Microsoft Internet Explorer. Browsers
make it very easy to move from Web site to Web site and back
again. You can use a browser to visit Web sites with search engines
that help you find what you want to see. Examples of sites with search
engines include: www.Yahoo.com,
www.Excite.com,
www.Lycos.com,
www.AltaVista.com,
www.Infoseek.com,
www.WebCrawler.com,and
www.Magellan.com.
