Accessing the Internet
The internet is a vast network of computers
linked to one another. The Internet allows
people around the world to share information
and ideas through Web pages, newsgroups,
mailing lists, chats, email, and electronic files.
Connecting to the Internet requires special
hardware and software and a Internet Service
Provider. Before you can use the internet, your
computer needs to be connected and you
should know how to access the Internet.

computers that share information by
means of hypertext links or “pages.” The
Internet is its carrier. To identify
hypertext documents, the Web uses
addresses called Uniform Resource
Locators (URLs). Here are some
example of URLs:

The Favorites button shows a list to

that you can return to them easily. The
History allows you to see previous sites

Web Browser
To view hypertext document on the
Web, you need special software. A Web
browser is software used to display Web
pages on your computer monitor.
Microsoft's Internet Explorer is a browser
for navigating (moving around) the Web
that is packaged with the Microsoft Office
Suite.

Dial up or Direct?
Dial-up access uses a modem and a
telephone line to communicate between
your computer and the Internet.
Direct access uses a special high-speed
connection, such as a DSL cable,
between your computer and the Internet.
This access is much faster, but usually
costs more.

about Search Engines. Search Engines
organize sites (URLs) into categories
using key words.
 Some of the most popular Search
Engines are Yahoo, Google, Lycos, Ask,
WebCrawler, Bing, DogPile and Excite.

History of the Internet
The Internet has its roots in the U.S.
Department of Defense, when in 1986, it
formed the National Science Foundation.
The NSF created the U.S. portion of the
Internet with high-speed, long-distance
lines. In 1991, the U.S. Congress further
expanded the Internet’s capacity and speed
and opened it to commercial use. Now over
200 countries now have Internet access.
