* [Show Transcript] REQUIREMENTS FOR AN INTERNET CONNECTION

To connect to the Internet, you need a computing device, a connection
device, and an Internet Service Provider (ISP).

The computing device can be a personal computer, a portable computer, or
even a mobile device, such as a cell phone or a handheld device.

You need a connection device, such as a modem, to connect your computer to
the Internet. A modem converts digital information into analog information
and transmits it over a phone line. A modem can either be built-in your
computer, or externally attached to it.

An ISP is a company that provides Internet connectivity to individuals,
businesses, and organizations. It may also provide additional services such
as the storage space to share your personal content.

There are different methods by which you can connect to the Internet. When
you connect to the Internet by using cables, the connection is called a
physical connection.

You can also connect to the Internet by using wireless technology. A
computing device that supports wireless technology has a Wireless Fidelity
or the Wi-Fi card that provides wireless communication between the
computing device and the network. A Wi-Fi card is not physically connected
to an ISP.

Another device you need for wireless connectivity is an access point (AP).
An AP is used to connect a wireless computing device to a wired network.
This wired network may belong to an ISP. You can then connect to the
Internet through the ISP. GLOSSARY
