What is Mac address and why it is required?

Answer 1

A Media Access Control address is given to every networking adapter. It is unique on every device. t is used as a permanent identifier for that component. For more info, check out the Wikipedia... http://en.wikipedia.org/wiki/MAC_address

Answer 2

A MAC address (also called an Ethernet address or an IEEE MAC address) is a number (typically written as twelve hexadecimal digits, 0 through 9 and A through F, or as six hexadecimal numbers separated by periods or colons, i.e. 0080002012ef, 0:80:0:2:20:ef) which uniquely identifes a computer that has an Ethernet interface. Unlike the IP number, it includes no indication of where your computer is located. In DHCP's typical use, the server uses a requesting computer's MAC address to uniquely identify it.
It is a unique number which is assigned to every piece of technology.

Answer 3

A MAC address is the serial number of a network card - or a similar identification number used in other machines, including switches and routers.

A switch is supposed to forward a frame only to the port (or interface) where the destination is connected. To do this, the switch consults its MAC address table - a table which lists which MAC address is connected to which port. The switch gets this information from previous transmissions done by the computers that communicate between themselves. Initially (for example, after a restart) the switch doesn't have this information, so it has to send frames out of all its ports.

Answer 4

The Media Access Control address (MAC address) is a unique identifier created by the manufacturer of equipment for identification of the equipment when connected to a network. t may also be known as an Ethernet Hardware Address (EHA), hardware address, adapter address, or physical address.

Answer 5

Every piece of hardware that is capable of talking to the internet (the WiFi board or the Ethernet board) has built into it a number that uniquely identifies it. This number is used by the LAN to identify which machines have been assigned which IP addresses and it is called the MAC address.

Try this:- (Windows operating system)

1) Open a terminal window (Run - cmd)

2) in the terminal windows type "ipconfig/all"

This will print out the MAC addresses in use on your computer)

Answer 6

A MAC (short for Media Access Control) address is a unique ID of an individual computer or other object with a network adaptor.

Answer 7

To assign a unique, permanent hardware address to every network device produced.

The MAC address is also used in layer 2 routing.

Answer 8

MAC address is a number created by the manufacturer to identify the computer on the network.

Answer 9
