Distinguish, differentiate, compare and explain what is the Difference between Routers and Bridges. Comparison and Differences.
Bridges
Bridges operates in both the physical and the data link layer. As a physical layer device, it regenerates the signal it receives. As a data link layer device, the bridge can check the PHYSICAL/MAC addresses (source and destination) contained in the frame. A bridge has a table used in filtering decisions. It can check the destination address of a frame and decide if the frame should be forwarded or dropped. If the frame is to be forwarded, the decision must specify the port. A bridge has a table that maps address to ports. Limit or filter traffic keeping local traffic local yet allow connectivity to other parts (segments).
Routers
Routers are identified as Layer-3 devices, as routers process logical addressing information in the Network header of a packet (such as IP addresses).
Difference between Routers and Bridges
| S.No. | Routers | Bridges |
| 1 | Router operates in network layer of OSI Model. | Bridge operates in data link layer of OSI Model. |
| 2 | Use to connect the LAN and WAN. | Use to connect two different LAN segments. |
| 3 | Transmits data in the form of packets. | Transmits data in the form frames. |
| 4 | Reads the IP Address of a device. | Reads the MAC Address of a device.. |
| 5 | Has more ports compare to bridges. | Has only two ports. |
| 6 | Uses routing table for sending data. | Does not use any routing table for sending data. |
