MAC address is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the media access control protocol sub-layer. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. It may also be known as an Ethernet Hardware Address, hardware address, adapter address, or physical address.

When and where can use the IP-address and the MAC-address?
802.11 use MAC addresses, which are the same as IP addresses in some networks
How many Mac addresses are possible?
This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.
Which protocol is used to convert logical IP addresses to physical MAC addresses?
Address Resolution Protocol (ARP)ARP is primarily used to translate IP Addresses to Ethernet MAC Addresses.
Do routers need MAC addresses?
yes they do.
Which protocol maps known IP addresses to MAC addresses on a local network?
ARP
What are the consequences of using MAC addresses for routing in network layer routers?
Routers don't use MAC addresses for routing. They use IP address.
How many potential MAC address schemes are possible?
There are 2^48 (or 281,474,976,710,656) potential MAC addresses. MAC addresses are 48 bits long, allowing for a wide range of unique addresses to be assigned to network devices.
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 does switch' MAC address table keeps track of?
The switch keeps track of which computers (identified through their MAC addresses) are connected to which switch ports.The switch keeps track of which computers (identified through their MAC addresses) are connected to which switch ports.The switch keeps track of which computers (identified through their MAC addresses) are connected to which switch ports.The switch keeps track of which computers (identified through their MAC addresses) are connected to which switch ports.
What happens when Mac address is broadcasting?
if the mac addresses are broadcrk securiwoasting the there is no need of net
What protocol is responsible for resolving ip addresses to mac addresses for source hosts that knows ip addresses of the destination host but not the mac address?
ARP, or Address Resolution Protocol, defined by RFC 826.
How long are Ethernet Mac addresses?
Ethernet addresses are 48 bits long - not 32 bits long like IP addresses. Different single network standards have different address lengths. Ethernet addresses are called MAC addresses for other reasons, Media Access Control.
