Layer 2 of the OSI model, the Data Link Layer is composed of two sublayers, the lower being the MAC layer that regulates how computers access information on a network and transmit it. A bridge connects two networks, or two sections of a LAN, and works at the Data Link Layer to regulate it.
1. Repeaters (Operate at the OSI Physical Layer).2. Bridges (Operate at the OSI Data Link Layer).3. Routers {and Brouters} (Operate at the OSI Network Layer).
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
Layer 2, the data-link layer.
Bridges and switches operate at the same OSI layer - layer 2. That means they switch packets based on the destination MAC address. A switch is sometimes called a multi-port bridge.A bridge has 2 ports, whereas a switch can have many more than that.
Layer 2 , Data Link Layer
Bridges primarily operate at the Data Link Layer (Layer 2) of the OSI model and use MAC (Media Access Control) addresses to forward data frames between different network segments. By analyzing the MAC addresses in the Ethernet frames, bridges can determine whether to forward or filter traffic, thereby reducing collisions and improving overall network performance. They do not use IP addresses, which operate at Layer 3, and are primarily concerned with local network traffic.
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
