Consider a 50 kbps satellite channel with a 500 milliseconds round trip propagation delay. If the sender wants to transmit 1000-bit frames, how much time will it take for the receiver to receive the frame?

(A) 250 milliseconds

(B) 20 milliseconds

(C) 520 milliseconds

(D) 270 milliseconds

Answer:

The correct answer is (D).

Explanation:

Given,

Bandwidth = 50 kbps

Round Trip time = 500 milliseconds = 2 * propagation time

So, propagation time = 250 ms

Transmission Time = data size / bandwidth = 1000 bits / 50 kbps = 20 ms

Hence, Time Taken by receiver to receive the frame ==> 250 ms + 20 ms = 270 ms.
