Please Answer ASAP

(40=20+20) A-to-B data link layer communications channel has a bit rate of 4Kbps, A-to-B propogation delay 20 msec, B-to-A delay the same, frame size 160 bits and stop-and-wait (that is, 1-bit sliding window, Protocol 4) protocol is used.

(i) Assuming simplex data channel, that is no reverse data traffic, immediate individual ack and ignorable ack transmission time, compute the channel utilization. Show your work.

(ii) Assuming full-duplex channel, the same frame size in reverse direction and immediate piggybacked ack, compute the channel utilization for full-duplex channel. Show your work.
