Exploring Your Computer’s Features
An overview of using the Internet
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
Once you have established an ISP account, you can connect to the
Internet.
If you are using your computer at the office, then you probably
connect to the Internet through your company’s network. See your
network administrator about connecting to the Internet.
Surfing the Internet
Once connected to the Internet, the Web browser displays a home
page, for example, your ISP’s home page on the Internet or your
company’s Web site home page.
To visit a desired Web site, type in the Web address. The Web
address, or Uniform Resource Locator (URL), is a unique identifier
for that computer system linked to the Internet. Web addresses can
also appear within a Web page’s text, and are known as links.
