Answer:

Selective Repeat protocols

Explanation:

It is better to make use of the selective repeat protocol here. From what we have here, there is a high error rate on this channel.

If we had implemented Go back N protocol, the whole N packets would be retransmitted. Much bandwidth would be needed here.

But we are told that bandwidth is limited. So if packet get lost when we implement selective protocol, we would only need less bandwidth since we would retransmit only this packet.

Correctly position the platen of the printer to hold the paper in place.

Explanation:
