Token Ring Network
Question 1 
In a token ring network the transmission speed is 10^{7} bps and the propagation speed is 200 metres/μs. The 1bit delay in this network is equivalent to:
500 metres of cable.  
200 metres of cable.
 
20 metres of cable.  
50 metres of cable.

Question 1 Explanation:
T_{t}= L / B => 1/ 10^{7} = 0.1 microsec
Given T_{p}= 200 m / microsec
In, 1 microsec it covers 200m
Therefore, in 0.1 microsec it is 200 * 0.1 = 20 meters
Given T_{p}= 200 m / microsec
In, 1 microsec it covers 200m
Therefore, in 0.1 microsec it is 200 * 0.1 = 20 meters
