Q
Which strategy is used by the pure aloha to prevent the congestion caused by continuous re-transmitted frames?
AA. Aborts the re-transmission after 5 attempts
BB. A station is allowed to re-transmit for 2 times
CC. Restriction on the attempts for re-transmission
DD. Re-transmission has no restriction
Correct Answer:
C. C. Restriction on the attempts for re-transmission
Explanation:
If a station re-transmits a frame more than the times, that is defined by the pure aloha, then pure aloha will abort the process re-transmission of the particular frame. The station needs to try after sometime later to send the frames.
