Ethernet (10/100Base-T)
Your computer comes with built-in 10/100 megabit per second (Mbps) Base-T (twisted-
pair) Ethernet networking capability, which you can use to connect to a 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 electronic mail; or
connect to the Internet. You can also share files between two computers or set up a
small network. The Ethernet port on your iMac G5 automatically detects other Ethernet
devices. You don’t need a crossover cable to connect to other Ethernet devices.
• Use 4-pair category 3 (Cat 3) Ethernet cables to connect to a 10Base-T Ethernet
network.
• Use 2-pair category 5 (Cat 5) Ethernet cables to connect to a 10Base-T or a 100Base-T
Ethernet network.
