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 91).
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.
 Dial-up connection—An external modem is plugged into a USB (d) port on your
computer and a telephone cable connects the modem to a telephone wall jack.
