0. Consider two hosts X and Y, connected by a single direct link of rate 10⁶ bits/sec. The distance between the two hosts is 10,000 km and the propagation speed along the link is 2 x 10⁸ m/s. Hosts X send a file of 50,000 bytes as one large message to hosts Y continuously. Let the transmission and propagation delays be p milliseconds and q milliseconds, respectively. Then the vales of p and q are:

Array

Option : D
Explanation :

B = 10⁶bits/sec
d = 10,000km = 10⁴ x 10 ³m
V = 2 x 10⁸ m/s
L = 50,000 Bytes
∴ Transmission time (p) =
= 400 ms
∴ Propagation time (q) =
= 50 ms
