Chapter 3 Using Your Computer 43
Ethernet (10/100/1000Base-T)
Your computer comes with built-in 10/100/1000 megabit per second (Mbit/s) twisted-
pair Ethernet networking capability, which you can use to connect to a network,
including a Gigabit Ethernet network, or to a cable or DSL modem.
Connecting to a network gives you access to other computers. You may be able to
store and retrieve information; use network printers, modems, and email; or connect to
the Internet. You can also use Ethernet to share files between two computers or set up
a small network. The Ethernet port on your PowerBook automatically detects other
Ethernet devices. You don’t need an Ethernet crossover cable when connecting to
other Ethernet devices.
 Use 2-pair category 3 (or higher) Ethernet cables to connect to a 10Base-T Ethernet
network.
 Use 2-pair category 5 (or higher) Ethernet cables to connect to a 100Base-T Ethernet
network.
 Use 4-pair category 5 (or higher) Ethernet cables to connect to a 1000Base-T Ethernet
network.
For More Information on Using Ethernet
Additional information, including setting up an Ethernet network and transferring files
