In networking, why two different types of addresses are used namely physical and logical for data transmission to take place between two computers?

Question

Accepted Answer

Physical addresses are used for identifying network devices, while logical addresses are used for identifying network applications.

Physical addresses are also known as MAC addresses and are unique identifiers assigned to network interface cards (NICs) by the manufacturer.
Logical addresses are also known as IP addresses and are assigned to network applications by the network administrator.
Physical addresses are used at the data link layer of the OSI model, while logical addresses are used at the network layer.
Physical addresses are used for local communication within a network, while logical addresses are used for communication across different networks.
Examples of physical addresses include 00-1B-44-11-3A-B7, while examples of logical addresses include 192.168.1.1.
