Explanation:
A bridge is a network device that connects two similar network segments together. The primary
function of a bridge is to keep traffic separated on both sites of the bridge. Traffic is allowed to pass
through the bridge only if the transmission is intended for a station in the opposite side. Bridges
operate at the data link layer of the OSI model an provides two different collision domains in
Ethernet, but they only provide one broadcast domain for layer 3 an up of the OSI model. The bridge
can store frames and forward them in many forms like Cut-through and Store and Forward.
