A bridge is a device that joins networks to create a much larger network. Both networks retain the same network addressing scheme, and broadcasts on one network will propagate across the bridge if the address of a frame matches the address of a workstation on the other side of the bridge. A learning bridge, also called an adaptive bridge, "learns" which network addresses are on one side of the bridge and which are on the other so it knows how to forward packets it receives. See "Bridges and Bridging."
