Physical vs. Logical Addresses Continued
When TCP/IP is used on an internetwork, the logical address is known as an IP address.
Routers utilize the IP address to route packets to the correct network segment.
The MAC address is implemented in hardware but the logical address is implemented in software.
Bridges and switches use the physical address at the Data Link layer but routers use the logical address at the Network layer.
The structure of a logical address makes it possible for devices to be uniquely identified on the network.
