Definitions for "Hardware Address"
also called physical address. The hardware address is associated with a particular network device.
The hardware address is also referred to as the physical address or MAC address and consists of a dozen hexadecimal digits (0-9 and a-f) typically expressed in six pairs of hex digits separated by hyphens. This address is often printed on the wireless card/device itself and can usually also be found through the software that configures your device.
The physical address for the NIC (network interface card). Used by the low-level hardware layers of a network. TCP/IP's ARP protocol translates IP addresses into hardware addresses. The NIC vendor gets the address from the IEEE and assigns it permanently to the NIC. Also called the MAC (Media Access Control) address.
