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?
