Please include working too! Thank you! :)

magine that you have conducted an experiment to send some data using a full duplex l protocol (as discussed in lectures). The link that you used has 10 Mb/s capacity, you were sending the data in frames of 1400 bytes, and receiving an AC ink from location A to location B, 1540 kilometres away, using the Simple K/NAK frame of bytes. Please assume the speed of propagation in the medium is 2x108 m/s. The following TWO questions relate to this experiment 11. Assume that you sent 30 frames back-to-back, and that no NAK frames were received in response, so the A-B link's loss probability was 0. How long should it take to send all 30 frames? Express the time in milliseconds. A. 11.91 B. 41.35 C. 33.65 D. 49.05 E. 19.61 12. Now you realise that the A-B link's loss probability has changed. You measure the link's loss probability, and find that it is now 0.1. Assume that you will send 30 frames and that for each frame, if you receive a NAK you will resend the frame, and continue to do that until you receive an ACK. At every stage, consider only whole frames for re- sending. What would have been the effective bit rate for this transfer? Express the rate in Mb/s. A. 7.51 B. 52.41 C. 9.08 D. 6.41 E. 72.63
