A Bridge is a networking device that connects multiple LANs to create a single, aggregated network segment. This process of aggregating networks to form a larger LAN is known as Network Bridging. Bridges work as the layer 2 network or data link layer of the OSI model and transmit data as data frames.
A wireless bridge connects networks having wireless segments. Bridges help improve network performance by separating a network into different sections or segments with different bandwidth. It can block or forward the incoming data frame after inspecting it for the destination MAC address. Switches are preferred over bridges in modern LANs as bridges generally connect fewer networks.
