The Internet is a worldwide network that links billions of smaller computer networks to one another. It allows billions of people to communicate with each other. In fact, right now Iím communicating with you on the Internet by telling you about the Internet.
The Internet is hooked up in a variety of
ways. For instance, the Internet can be connected to your computer by
dial-up or broadband (DSL or cable modem). Another way of connecting to
the Internet is by satellite. This allows
people to use wireless Internet communication. That way if you donít
have land based communication lines, like cable or telephone lines, you can
use satellites. The Internet is not maintained by one person or by a
certain company. In a way, it is maintained by everyone who uses
E-mail is a way of sending people mail
over the Internet. People like e-mail
because itís immediate. Some people are calling the postal service snail
mail because itís a lot slower than the Internet. It is estimated that

use the Internet for research. To locate information on the Internet,
people use search engines. If you donít know how to do a search, Iíll
explain it. Letís say you need information for a report. You go to a
search engine (such as Yahooligans
or Google) and type in the subject of
your report. Next,

of the Internet all began with President Eisenhower. He created the Advanced
Research Projects Agency (ARPA) in 1958.
President Eisenhower was afraid that the United States was falling
behind the Soviet Union. In 1962, ARPA was still developing when an MIT graduate student named Leonard
Kleinrock invented the technology of the Internet.
Then in 1966 ARPA quickly got back into the action and formed the ARPAnet. This became the start of the Internet.
The technological innovations that were to follow are mind boggling, but
here are some important highlights. Even
though the main participants in the network were universities and research
organizations, other educational groups and commercial organizations
wanted to participate as well. In 1973, Ray Tomlinsonís efforts produced
e-mail. In 1989, Tim BernersĖLee (a scientist) proposed the World Wide
Web Project. Not too much later a browser called Mosaic was created by a
group of University of Illinois students led by Marc Andreessen in 1993.
Netscape and Microsoft followed with their own browsers. Now just about
anyone can surf the Internet.
Even though itís fun to look up things, talk to friends, and do other things like that, you still have to be SAFE! Here are some websites to learn more about how YOU can be safe on the Internet.
