Learning about the Internet
The Internet is a worldwide network of computers linked together to provide
information to people everywhere. The two most popular services on the
Internet are e-mail and the World Wide Web. You can access this network by
connecting your computer to a telephone line and signing up with an Internet
Service Provider (ISP).
If you want to access the Internet you need:
■ A modem – a device that connects your computer, using a telephone line,
to other computers or servers. If you have a modem jack on your
computer, you have a modem.
■ An Internet Service Provider – a service that provides access to the Internet
through an ISP server. When you connect to an ISP, the ISP server lets you
access the Internet and your e-mail messages.
■ A Web browser – a program that displays information from the World
Wide Web.
■ An e-mail program – a program that lets you create, send, and receive
e-mail messages over the Internet.
