Several statements regarding MAC protocols are give below. Indicate the TRUE statements. All packets are assumed to be of fixed size and take exactly one unit of time to transmit.

[Answer the question above by selecting out of the following, the true statements]

-- T/F --- in slotted Aloha, nodes begin to transmit only at certain time instances.

-- T/F --- In slotted Aloha, a node's transmission is successful if there is no transmission by other nodes in the time unit prior its transmission and in the time unit during its transmission.

-- T/F --- In Ethernet protocol, a node encountering a busy channel, transmits after the channel is sensed to be idle without using any random backoff.

-- T/F --- In Aloha and slotted Aloha, a node retransmits its frame immediately after encountering collision to keep the channel busy. In Aloha protocol, nodes transmit when they sense the channel to be idle.

-- T/F --- In Ethernet protocol, nodes that encountered collision to their transmissions back off for random amount of times based on their frame types.

-- T/F --- In Token Ring, loss of the token is a single point of failure.

-- T/F --- In Aloha protocol, a node's transmission is successful if there is no transmission by other nodes in the time unit prior its transmission and in the time unit during its transmission.

-- T/F --- In Aloha protocol, nodes are assumed to detection collision.

-- T/F --- Master-slave protocol is useful when there are multiple peer devices that communicate infrequently.
