The address for a device as it is identified at the Media Access Control (MAC) layer in the Ethernet networkarchitecture. The MAC address is usually stored in ROM on the network adapter card and is unique.
When reaching another host on your own network, or when accessing a router on your network to reach another network, The IP address (4 numbers separate by dots) is converted to the MAC address of the host or router on your network. When the message or packet(S) are sent out, the device with that destination MAC address recognizes that it was meant to receive the message and accepts it. Any other device on the network that can see the transmission is expected to ignore it.
An exception is a device or router that is configured to be "promiscuous". Such a machine will also accept and process all transmissions even if meant for another device. This is often used for network monitoring/logging, maintenance, and problem resolution.
Although the MAC address is hard coded into the network interface or device, in almost all cases it can be changed. An example for this is when an ethernet network is used with the DECnet protocol. DECnet can be used instead of or togetherwith TCP/IP (or Netware or NetBEUI). The DECnet protocol requires that the MAC address be changed to incorporate the DECnet address as part of the MA address.
A MAC address is the serial number of a network card - or other equipment that connects to a network, usually an Ethernet network. In an Ethernet network, the MAC address is used as source and destination address, to know who is communicating with whom. For example, a switch uses the MAC address to forward a frame (a pieces of data) to the correct computer.
What else can I help you with?
Which criteria does the switch use to build dynamic Mac table?
address resolution protocol is used when the switch used to build the dynamic mac address table.
What number system is used for the Mac Address?
decimal
What is commonly used to restrict access to a network based on the physical hardware address of the clients network device?
You can enable MAC address (also know as Physical Address) filtering. MAC address filtering has two modes: 1. Allow access to listed MAC addresses 2. Deny access to listed MAC addresses.
Does MAC address operates at Layer 2?
yes. thougth the nic is a layer 1 device its mac address is used in datalink layer
6 Which type of address is used in an Ethernet frame header?
Mac address only!
Which two statements describe the operation of an access layer ethernet switch choose two?
The source MAC address within a frame is used by the switch to associate a port with that MAC address. Frames are directed by the switch from one port to another based on the destination MAC address within the frame.
What is a private MAC address?
A MAC address is unique to your ethernet card. MAC addresses are used within an Ethernet network to uniquely identify the source and destination of Ethernet frames. ARP (Address Resolution Protocol) is used on IP networks to map IP addresses to MAC addresses within an Ethernet network.
What is the command used to find the MAC address of the NIC?
ipconfig
What is the Mac broadcast address?
Ff:ff:ff:ff:ff:ff
Do A MAC address is used to identify Macintosh computers?
MAC stands for media access control adress
How can you got the Mac Address?
Any network card has its own MAC address, so it doesn't require an extraordinary effort to have your own MAC address. The MAC address is the serial number of the network card.Any network card has its own MAC address, so it doesn't require an extraordinary effort to have your own MAC address.

Is Mac address hardware address?
99% of the time, yes. There is the ability on a network adapter to over-ride the mac-address that comes with it, but very rarely is that feature ever used. fm
