Definitions for "Transparent Bridge"
A bridge that is used to form an extended LAN consisting of a tree structure in which only one active path connects any two stations in the extended LAN. Stations on the interconnected LANs are not aware of the presence of transparent bridges. Transparent bridges learn appropriate routes for messages by observing transmissions that take place on the LANs to which they are connected and forwarding messages that they receive to the opposite network when required.
Level 2 bridges used with Ethernet networks. They are transparent in that hosts need not know any addressing information in order to pass messages through the bridge.
a device that can be used to divide up an Ethernet network to reduce collisions
