What is the Information Superhighway?
The part of the Information Superhighway that
is most often referred to in the popular media is the Internet. "Going
online" refers to getting connected to the Internet or other commercial service,
usually via a telephone line.

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.
