The Internet 
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 
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. 
Internet Service Providers 
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.
Connecting to the Internet 
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
