A bridge is one of the network devices in computer networks to connect two or more communication networks or network segments and creates a single network. It provides interconnection with other computer networks, which use the same protocol. The multiple local area networks (LANs) can be connected to form a larger local area network.

In simple words, a bridge in computer networks is defined as, the network device that provides a connection between two local area networks (LANs) or two segments of the same local area network. It is also known as an adobe bridge or network bridging. It operates under the data link layer of the OSI model, hence referred to as layer 2 switches.
