The Internet
A network is created when two or
more computers are connected to
each other to share information.
The Internet
Networks can be also be connected
together to share information and
computing power.
The Internet
The Internet is the global network of
networks, connecting computer
networks across the country and
around the world.
The Internet
Computers in a network that is
connected to the Internet can
communicate with other networks
and computers that are also
connected to the Internet.
The World Wide Web
The World Wide Web is the part of
the Internet which presents electronic
information in an interactive format.
The World Wide Web
The World Wide Web is made up of
web sites. Each web site has one
or more web pages.
The World Wide Web
Anyone can have a web site:
The World Wide Web
Web pages contain special areas called
hyperlinks. These links can appear as
underlined words. Pictures or images
on the page can also be hyperlinks.
Clicking on a hyperlink will take you to
another web page.
The World Wide Web
Everything on the World Wide Web has
a unique location. You can go directly
to a web page by typing in its exact
web address. Web addresses look like
this:
www.google.com
www.usa.gov
myflorida.com
www.palmbeach.k12.fl.us
The World Wide Web
Web pages are stored on special
computers called web servers.
While the Internet and World Wide
Web are always available,
sometimes individual web servers
experience technical problems.
The World Wide Web
When there is a
problem with a
web server, web
pages stored on
it may be
temporarily
unavailable.

Internet Service Providers
Before you can visit a web site, you
must be connected to the Internet.
Internet Service Providers
If you are at the Library, you may
access the Internet through the
Library’s WiFi service, or by using
the Library’s computers.
Internet Service Providers
To access the Internet from home,
you must use an Internet Service
Provider (ISP).
Internet Service Providers
Internet Service Providers charge a fee
for providing Internet access. Prices
vary depending on the service package
and the type of connection.
Internet Service Providers
The fee charged by the ISP for
Internet access will vary depending
on:
•Type of connection
•Speed of the connection
•Length of time (on the Web)
Internet Service Providers
The typical choices for home users are:
Dial up access, using a telephone
line.
High speed access, using either
Cable or telephone lines.
Wireless access, using a cellphone
service.
Internet Service Providers
Dial up access uses a telephone
modem to convert signals to and
from the computer.
Most computers today
have telephone
modems built in.
Internet Service Providers
High speed Internet access through
DSL (Digital Subscriber Line) or
Cable require a special modem,
usually supplied by the ISP.
Internet Service Providers
A dial up connection to the Internet
requires the computer “dial” into the
ISP’s network through the modem.
The connection
lasts only as long
as the modem’s
telephone
connection is
active.
Internet Service Providers
A high speed connection to the
Internet typically maintains the
connection as long as the cable or
phone line is plugged into the
modem. With this type of service,
the Internet is “always on.”
Internet Service Providers
Internet service through an ISP
usually includes:
Multiple e-mail accounts
Space to post personal web
pages
Internet Service Providers
If you do not have, or want, Internet
access at home, one option is to use
computers at your local Library.
Libraries do not provide email
accounts, however, or space for
personal web pages.
