In a token ring network the transmission speed is 10$^7$ bps and the propagation speed is 200 meters/$\mu$s. The 1-bit delay in this network is equivalent to:
500 meters of cable.
200 meters of cable.
20 meters of cable.
50 meters of cable.
As, token ring network
So, transmission delay = length / bandwidth
transmission delay = 1/10^7 = 0.1micro sec.
as, propagation speed =200m/micro sec.
In , 1micro sec. it covers 200m
than in 0.1micro sec. it is 20metres.(C) answer
There is one more problem. Ppl who have...
