How to find delay in token ring network,general expression?


#1

In a token ring network the transmission speed is 10^7 bps and the propagation speed is 200 metres/micro second. The 1-bit delay in this network is equivalent to:

a) 500 metres of cable.
b) 200 metres of cable.
c) 20 metres of cable.
d) 50 metres of cable.


#2

As, given token ring network
So, transmission delay = length / bandwidth
transmission delay = 1/10^7 = 0.1 micro sec.
as,
propagation speed =200 m/micro sec.
so In ,
1 micro sec. it covers 200 m
than in 0.1 micro sec. it is 20 metres. © answer
