Hi Pushkar,

Im not sure if i am in the correct forum to ask this question however I'll post the question anyways and if im not in the correct area please advise for future reference.

I am currently learning CCENT and am on the OSI model. In the text regarding MAC addresses:

"Although the source address will always be a unicast or single destination address, the destination address can be unicast , multicast (a determined subset of nodes), or broadcast (all nodes in a broadcase domain) address"

I understand the first part, a MAC address on the source PC is a single destination address on a LAN but the second part is confusing. Is it saying the although the MAC address on the LAN a single address, it can be a part of a multicast (group of nodes) or a broadcast (all nodes). Or has the single MAC address have other capabilities being a multicast and broadcast? Im confused!!

Cheers,
Norbert
