understand multicast and retransmission
Homework Answers
Multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution.Multicast should not be confused with physical layer point-to-multipoint communication.
Retransmission, essentially identical with Automatic repeat request (ARQ), is the resending of packets which have been either damaged or lost. Retransmission is one of the basic mechanisms used by protocolsoperating over a packet switched computer network to provide reliable communication (such as that provided by a reliable byte stream, for example TCP).

An IEEE 802.3 MAC Frame has 8 octet addresses. A message may be unicast, multicast, or broadcast. If the LSB of the first octet of the destination address is 0, the address is unicast; otherwise it is multicast. A broadcast message has all 1s in its address. If destination addresses of three messages are 4B:6A:03:49:5C:F0:44:A6:05:E5:32:0B , and FF:FF:FF:FF:FF:FF, state their types.
