Networking Terms
What is a node?
A node is any given device that resides or is connected onto an existing network. A computer with a network
card connected to a switch is a node. The same thing applies to a Mac connected to a hub.
What is a bridge?
A bridge is used when connecting one side of the network with another network. Previously, connecting
every computer together with the other network would mean having cables all over the place. Instead a
bridge was brought in to have 1 connection between the networks instead of 20. The bridge in the Home-
Plug terms functions like a concentration device that connects many computers onto the HomePlug network
using 1 HomePlug device.
How do I know if I require a node or a Bridge?
If you want to connect only one computer to the Power line network, you need a node. If you plan to con-
nect a group of computers currently not HomePlug ready to the Power line network, you need a bridge. The
HomePlug USB adapter can only be used as a node. The HomePlug Ethernet Bridge can be used as either
a node or bridge. It is designed as a bridge in default; the only way to turn it off is to install the utility software
that comes with the unit. That will turn the bridge into a node.
