The Internet is an association of thousands of networks and 
millions of computers around the world connected by 
communications lines. They all work together to share information. 

The World Wide Web (or “Web”) is a subset of the Internet—a 
collection of interlinked documents (located on computers 
connected to the Internet) that work together using a specific 
Internet protocol called Hypertext Transfer Protocol (HTTP). 

The World Wide Web offers information as text, images, audio, or 
video to be referenced from anywhere in the world. Special 
programs called Web browsers are specifically designed to work 
with HTTP. They make it easier to connect to a particular network 
address and send and receive information. 

To connect a computer directly to the Internet, many people and 
businesses use an Internet Service Provider (ISP). An ISP is a 
company that has the equipment and the telecommunication lines 
necessary to maintain an Internet connection. 

You can connect to the Internet by using a telephone and modem or 
through other higher-speed communication methods such as Digital 
Subscriber Lines (DSL), cable, and satellite links.

To connect to the Internet, you need:

❖

A modem and telephone line, or a LAN connection

❖

A Web browser 

❖

An Internet Service Provider (ISP) account

Once you have established an ISP account, you can connect to the 
Internet.

Connect your computer’s modem (available on certain models) 
to a telephone line. For more information on connecting a 
modem, see 

Start your Web browser. Have your modem dial the ISP’s 
telephone number, and establish a connection with the ISP’s 
computer.
