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.
