In a token ring network the transmission speed is 107 bps and the propagation speed is 200 meters/ μs. The 1-bit delay in this network is equivalent to:
- A.
500 meters of cable.
- B.
200 meters of cable.
- C.
20 meters of cable.
- D.
50 meters of cable.

Correct answer: C
First, calculate the transmission delay for a single bit. Given the transmission speed is 10^7 bps, the time to transmit one bit is 1 / 10^7 = 10^-7 seconds.
Next, convert the propagation speed to meters per second: 200 m/μs = 200 × 10^6 m/s = 2 × 10^8 m/s. Finally, multiply the propagation speed by the transmission delay to find the equivalent distance: (2 × 10^8) × (10^-7) = 20 meters.
