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.
  
1) In Ethernet protocol, nodes that encountered collision to their transmissions back off for random amount of times based on their frame types.

2) In Aloha protocol, nodes transmit when they sense the channel to be idle.

3) 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.

4) In Ethernet protocol, a node encountering a busy channel, transmits after the channel is sensed to be idle without using any random backoff.

5) 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.

6) In Aloha and slotted Aloha, a node retransmits its frame immediately after encountering collision to keep the channel busy.

7) In Aloha protocol, nodes are assumed to detection collision.

8) Master-slave protocol is useful when there are multiple peer devices that communicate infrequently.

9) In slotted Aloha, nodes begin to transmit only at certain time instances.

10) In Token Ring, loss of the token is a single point of failure.

1) It is true.

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

2) It is true.

In Aloha protocol, nodes transmit when they sense the channel to be idle.

3) It is true.

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.

4) It is true.

In Ethernet protocol, a node encountering a busy channel, transmits after the channel is sensed to be idle without using any random back-off.

5) It is true.

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.

6) It is false.

In Aloha and slotted Aloha, a node does not retransmit its frame immediately after encountering collision to keep the channel busy as the node waits.

7) It is true.

In Aloha protocol, nodes are assumed to detection collision before the transmission.

8) It is false.

Master-slave protocol is useful when there are multiple peer devices that communicate frequently.

9) It is true.

In slotted Aloha, nodes begin to transmit only at certain time instances.

10) It is false.

In Token Ring, loss of the ring is the single point of failure.
