Q:

Differentiate a MAC address and an IP address and describe how and when each address type is used in a network?

Answer

A MAC address is a hexadecimal number identifying the physical connection of a host. MAC addresses are said to operate on layer 2 of the OSI model. IP addresses, which can be expressed in binary or decimal format, are logical identifiers that are said to be on layer 3 of the OSI model. Hosts on the same physical segment locate one another with MAC addresses, while IP addresses are used when they reside on different LAN segments or subnets. Even when the hosts are in different subnets , a destination IP address will be converted to a MAC address when the packet reaches the destination network via routing.
