A media access control address (MAC address) of a device is a unique identifier assigned to a network interface controller (NIC). Cac for mac. For communications within a network segment, it is used as a network address for most IEEE 802 network technologies, including Ethernet, Wi-Fi, and Bluetooth. MAC address can be abbreviated as Physical Address What does Physical Address mean? - Definition of Physical Address - Physical Address stands for MAC address. Media Access Control (MAC) addresses, also called Ethernet addresses, are 6-byte-long (48-bit-long) binary numbers. For convenience, most computers list MAC addresses as 12-digit hexadecimal numbers. MAC addresses represent a single NIC or Etherne. A MAC address can go by other names, including physical address (in Windows), Ethernet address, and hardware address. Whatever you call it, this address is a 12-character hexadecimal string. The MAC address is usually assigned by the manufacturer of a Network Interface Controller (NIC), and it is stored in the hardware. The NIC is a computer circuit card that allows a computer to connect to a network.
What Does Mac Address Stand For In Computers
Stands for 'Media Access Control Address,' and no, it is not related Apple Macintosh computers. A MAC address is a hardware identification number that uniquely identifies each device on a network. The MAC address is manufactured into every network card, such as an Ethernet card or Wi-Fi card, and therefore cannot be changed.
Ip Address
Because there are millions of networkable devices in existence, and each device needs to have a unique MAC address, there must be a very wide range of possible addresses. For this reason, MAC addresses are made up of six two-digit hexadecimal numbers, separated by colons. For example, an Ethernet card may have a MAC address of 00:0d:83:b1:c0:8e. Fortunately, you do not need to know this address, since it is automatically recognized by most networks.
