Distinguish, differentiate, compare and explain what is the Difference between Routers and Bridges. Comparison and Differences.
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 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
|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.|
