MAC address

The hardware address of a device connected to a shared network medium. See also Media Access Control.

MAC address

(Media Access Control address) The unique 48-bit serial number in the network circuitry of Ethernet and Wi-Fi devices that identifies that machine from every other globally. Also used in earlier Token Ring networks, the ID is assigned to vendors by the IEEE and "burned into" most network adapters (NICs) at the time of manufacture. However, some NICs are programmable, and the possibility of having the same MAC address is theoretically therefore not impossible. See MAC layer, OUI and binary values.


Logical IP and Physical Ethernet
Each machine in an IP network has an IP address assigned temporarily by software (see DHCP) or permanently by the network administrator. The physical address is assigned by the manufacturer of the hardware. See IP address.







Wireless MAC Addresses
Smartphones have unique MAC addresses for Wi-Fi and Bluetooth as in this iPhone example. Like Ethernet, Wi-Fi also requires an IP address, which can be viewed in Settings. Bluetooth does not use IP addresses.

The product characteristics (components of the vector [X.sub.i]) include indicator variables for layer types (layer 3, layer 3 lite, layer 4; layer 2 is the omitted characteristic), indicator variables for the product series, the number of MAC addresses, the number of ports, and the switching capacity (measured in gigabytes per second).
Android P addresses this possibility by allowing the system to generate a new and random MAC address for every single Wi-Fi network you connect to.

However, nothing can be ascertained because Comelec does not have the records of the MAC addresses of their legitimate PCOS machines and computers nor the list of IP addresses that were assigned to the devices during the 2010 elections, Vitangcol said.

When a host on a local network wants to know the MAC address of the corresponding IP address, it broadcasts an ARP request message to all the hosts connected to the network.
[9] studied the function of MAC address in WSN and proposed a variable length MAC address encoding scheme, with which traditional fixed length MAC addresses are replaced by variable length local addresses which are coded in the Huffman encoding.
