C Connecting to the Internet
You can use your iMac to browse the World Wide
Web, send email to friends and family, and
conference in real time over the Internet. Use the
information that follows to connect to the Internet.
When you first start up Mac OS X, Setup Assistant helps you enter your Internet
configuration information. If you don’t use Setup Assistant to configure your Internet
connection, you can use Network Setup Assistant later (see “Using Network Setup
Assistant to Connect” on page 103).
There are four kinds of Internet connections:
 High-speed DSL or cable modem connection— Your computer is connected using a
special modem you get from an ISP using an Ethernet cable.
 AirPort Extreme wireless connection—Your computer is connected wirelessly to the
Internet using an AirPort Express or AirPort Extreme Base Station or another wireless
network.
 Local area network (LAN)—Your computer is plugged into a LAN using an Ethernet
cable. This type of connection is usually used in the workplace.
