Describe two scenarios that may require data retransmission.
What will be an ideal response?
If the data rate of the sender is greater than the data rate of the receiver, the receiver will not be able to copy the transmitted data in its buffer (memory storage) and therefore, the transmitted data will be lost and need to be retransmitted. Retransmission may also be necessary if: a) the receiver buffer size is not large enough to receive all of the transmitted data; b) the data becomes corrupt when it reaches the receiver; or c) the receiver’s acknowledgement message does not reach the transmitter.
