In a token ring network the transmission speed is 107 bps and the propagation speed is 200 m/μs. The 1-bit delay in this network is equivalent to _______
- A.
20 m
- B.
30 m
- C.
50 m
- D.
40 m
Attempted by 240 students.
Show answer & explanation
Correct answer: A
Answer: 20 m
Explanation:
Compute the duration of one bit: 1 / bitrate = 1 / 10^7 s = 10^-7 s = 0.1 μs.
Convert that time into distance using the propagation speed: distance = propagation speed × time = 200 m/μs × 0.1 μs = 20 m.
Therefore, the 1-bit delay is equivalent to 20 m of cable.
