Here again with these two questions
Q1.CSMA/CD network has slot time of 51.2?s.what would be the back-off delay time immediately after the fourth attempt?
i got 4096 but this wasn't part of the option given in my practice questions.
Q2.What would be the round-trip delay if 2 nodes are connected by 40m of cable to a repeater hub, where 2 repeaters are connected by 90m of cable.
Operating at 10Mbit/s
Velocity of propagation thro cable 1.80 X 10^8 m s -1
Delay throu each repeater 0.60?s
My answer to this was 17?s, i'm correct? please help me
