Consider a CSMA/CD network running at 10 Mb/s with the following operational setting: Interframe Gap (IFG) = 96-bit times Jam signal = 48-bit times The signal speed in the cable is 2 108 m/s There are two hosts P and Q attached to this CSMA/CD ... P and Q stop the transmission due to the collision? (3%) When will P and Q notice that the network turns idle after the collision?

What are contention periods in CSMA? Why are they used?
As far I know that, contention slots are required to avoid all channels from transmitting at the same time. But what happens when the contention slot is over? All stations will transmit together and it will lead to jamming of the channel then. What exactly is the role of contention slots and how does it avoid collisions?
