Concept:
- The bridge is used to connect similar LANs with the same protocols. A bridge operates at the data link layer. It is also used for interconnecting two LANs working on the same protocol. It has a single input and single output port, thus making it a 2 port device. A bridge must contain addressing and routing capability.
- A bridge is a network device that joins two or more LANs (local area networks) to build a larger LAN. Network bridging is the process of aggregating networks. A bridge joins the various components to make them appear as if they are all part of the same network.
Hence the correct answer is Bridges.

Connectivity Devices for LANs
There are several devices used to connect similar Local Area Networks (LANs) with the same protocols. These devices facilitate the transmission of data packets between different network segments. The options given in the question are gateways, routers, switches, and bridges. Among these options, the correct answer is bridges. Let's understand why bridges are used for this purpose.
1. Gateways:
- Gateways are used to connect networks with different protocols, translating data between incompatible systems.
- They are primarily used for interconnecting networks with different architectures, such as connecting a LAN to a Wide Area Network (WAN).
- Gateways operate at the network layer (Layer 3) of the OSI model.
- In the given question, where LANs with similar protocols need to be connected, gateways are not the appropriate choice.
2. Routers:
- Routers are used to connect networks and facilitate the exchange of data packets between them.
- They determine the most efficient path for data transmission based on routing tables.
- Routers operate at the network layer (Layer 3) of the OSI model.
- While routers are essential for connecting different networks, they are not specifically designed for connecting LANs with the same protocols.
3. Switches:
- Switches are used to connect devices within a single network or LAN.
- They operate at the data link layer (Layer 2) of the OSI model.
- Switches forward data packets based on MAC addresses, allowing multiple devices to communicate within a LAN.
- While switches are crucial for internal network connectivity, they are not specifically used to connect separate LANs with the same protocols.
4. Bridges:
- Bridges are used to connect similar LANs with the same protocols.
- They operate at the data link layer (Layer 2) of the OSI model.
- Bridges analyze the destination MAC address of incoming data packets and forward them only to the appropriate segment of the network.
- By filtering and forwarding data packets within the same network protocol, bridges effectively connect separate LANs with the same protocols.
Therefore, the correct device for connecting similar LANs with the same protocols is a bridge.
