Problem P19

Suppose nodes A and B are on the same 10 Mbps broadcast channel, andthe propagation delay between the two nodes is 245 bit times. Suppose Aand B send Ethernet frames at the same time, the frames collide, and thenA and B choose different values of K in the CSMA/CD algorithm. Assuming no other nodes are active, can the retransmissions from A and B collide? Forour purposes, it suffices to work out the following example. Suppose A and Bbegin transmission at t = 0 bit times. They both detect collisions at t = 245 bittimes. Suppose KA = 0 and KB = 1. At what time does B schedule its retransmission?At what time does A begin transmission? (Note: The nodes must waitfor an idle channel after returning to Step 2see protocol.) At what time doesAs signal reach B? Does B refrain from transmitting at its scheduled time?

Step 1 of 3

3.Process Management  A process can be thought of as a program in execution. A process will need certain resources—such as CPU time, memory, files, and I/O devices —to accomplish its task. These resources are allocated to the process either when it is created or while it is executing.  A process is the unit of work in most systems. Systems consist of a collection...
