The network physical address is usually encapsulated by a logic address, i.e. IP address, for the purpose of:
independence -- an abstract address based networks can hook any machines.
flexibility -- an abstract address based network architecture can be easily managed and maintained.

To form an Intranet network, computers are connected by physical cable and network cards. As each network card bears a globally unique identification number, computers can identify the others and be distinguished from each other. This unique card identification number is also referred to as physical address which usually takes the form like 00:4a:2e:43:57:04.
