Question
Which network device operates at the Data Link Layer of
the OSI model and helps to filter and forward data between LAN segments?Solution
A Bridge operates at the Data Link Layer (Layer 2) of the OSI model and is used to divide a local area network (LAN) into multiple segments. It helps reduce traffic by filtering data packets based on MAC addresses and forwarding them only to the intended segment. This improves overall network performance and minimizes collisions. Unlike a hub, which broadcasts data indiscriminately, a bridge ensures that packets are sent only to the relevant portion of the network. Why Other Options Are Incorrect:
- Hub: A hub is a Layer 1 device that broadcasts data to all devices connected to it, regardless of the destination. It does not filter or forward packets.
- Router: A router operates at the Network Layer (Layer 3) and is responsible for routing data packets between different networks using IP addresses.
- Switch: While switches also operate at Layer 2, they are more advanced than bridges and have replaced them in modern networks. However, switches can handle multiple ports, unlike a bridge, which typically connects two segments.
- Gateway: A gateway operates at higher layers of the OSI model and translates data formats between different networks or protocols. It does not perform Layer 2 functions.
