Demand priority

Heavy traffic can effectively bring standard Ethernet networks to a standstill, because nodes spend most of their time trying to access the network.

Digital subscriber line

For residential variations of DSL, this is usually the Ethernet (RJ-45) port or a USB port; in rare models, a FireWire port is used.

DSL modem

DSL routers, the most common form of DSL modem, the are external to the computer and wired to the computer's Ethernet port or its USB port, whereas voice-band modems are usually internal devices installed in the computer itself in a PCI interface slot in the back.

It usually also has a USB jack which can be used to connect to computers via a USB cable, to allow connection to computers without an Ethernet port.
