Suppose nodes A and B are on the same $100Mbps$ broadcast channel, and the propagation delay between the two nodes is

$450$ bit times. Suppose A and B send Ethernet frames at the same time, the frames collide, and then A and B choose different

values of $K$ in the CSMA$/$CD algorithm. $($In each step, explain in detail$)$

i$.$ Suppose A and $B$ begin transmission at $t=0$ bit times. At what time, do they both detect collisions?

ii$.$ Suppose $KA=1$ and $KB=0.$ At what time does $B$ schedule its retransmission? At what time does A begin

transmission?

iii. At what time does $B\text{'}$s signal reach $A?$

iv$.$ Assuming no other nodes are active, can the retransmissions from A and $B$ collide?

v$.$ Draw CSMA diagram showing the events between node A& B$.$
