Question

After 4th collision in ethernet, find the maximum time that the adapter waits until sensing the channel again for a 100 mbps broadcast channel?

Answer 1

Waiting time for a 100 Mbps broadcast channel is 0.512 ms

Recall that with the CSMA/CD protocol, the adapter waits K * 512 bit times after a collision,

where K is drawn randomly. For K = 100,

The one bit time for 10 Mbps is 1/10000000 s = 0.0001 ms

The one bit time for 100 Mbps is 1/100000000 s = 0.00001 ms

Waiting time for a 10 Mbps broadcast channel is K*512*0.0001= 5.12 ms

Waiting time for a 100 Mbps broadcast channel is K*512*0.00001= 0.512 ms

What is a collision in Ethernet?

A collision happens on a half-duplex Ethernet network when two devices on the same network attempt to communicate data at the exact same time. The two transmitted packets are "collapsed" by the network, which results in the network discarding both of them. On Ethernets, collisions are unavoidable.

How collision is avoided in Ethernet?

A collision is a momentary interaction between two bodies or more than two bodies at once that modifies the motion of the bodies involved as a result of the internal forces at work. Collisions entail the application of force (there is a change in velocity).
