finished? 2) Suppose we want to transmit the message 10011010 and protect it from errors using the 4 degree polynomial x4 +x2+x11. Use polynomial long division to determine the message that should be transmitted. a) b) Compute the CRCs above and explain whether your results are consistent with your answer above. 3) Let A and B be two stations attempting to transmit on an Ethernet network. Each hasa steady state queue of frames ready to send:A's frames will be numbered 1. A2, and so on, and B's similarly. Let T-51.2us be the exponential backoff base unit. Suppose A and B simultaneously attempt to send frame 1, collide, and happen to choose backoff times of OxT and 1xT, respectively, meaning A wins the race and transmits Al while B waits. At the end of this transmission. B will attempt to retransmit B1, while A will attempt to transmit A2. These first attempts will collide, but now A backs off for either OxT or 1x7 while B backs off for time equal to one of OxT, 3xT a) Give the probability that wins this second backoff rate immediately after this first collision, that is, A's first choice of backoff time kx51.2 is less than B's Suppose A wins this second backoff race. A transmits A3, and when it is finished, A and B collide again as A tries to transmit A4 and B tries once more to transmit B1. Give the probability that A wins this third backoff rate immediately after the b)
