Consider a CSMA / CD network that transmits data at a rate of 100 Mbps (108 bits per second) over a 1 km (kilometer) cable with n repeaters. If the minimum frame size required for this network is 1250 bytes, what is the signal speed (km /sec) in the cable?

Option A. 8000
Option B. 10000
Option C. 16000
Option D. 20000
True Answer D

Explanation :

 Data should be transmitted at the rate of 100 Mbps. For a collision to be detected, the frame size should be such that the transmission time of the frame should be greater than twice the propagation delay.
Transmission Time >= 2*Propagation Time
=> 1250*8 / (100 * 10^6) <= 2*length/signal speed
=> Signal speed <= (2 * 10^3 * 100 * 10^6) / (1250 * 8)
<= 2 * 10 * (10 ^ 3) km/sec
<= 20000
