Repeaters and bridges work as interconnection devices in computer networks. They operate in different layers of the OSI model.

- Repeaters and hubs (multiport repeaters):
These devices operate at the physical layer. They forward physical signals.

- Bridges and switches (multiport bridges):
These devices operate at the data link layer. A bridge is a type of network device that can understand the data link frames it receives. This understanding allows bridges to make decisions based on the information within those frames, such as filtering frames based on their MAC address
