Question 65

In a system with the network configuration show below, the same size message data was sent and received between the host computer and two terminals. The turnaround time required for sending and receiving data between the host computer and terminal A was 450 milliseconds, and 700 milliseconds for terminal B. When the size of upload and download messages and the processing time required by the host computer for both terminals A and B is the same, how many milliseconds does it take for one-way transmission from terminal B to the host computer? Here, the turnaround time means the period of time beginning when the terminal starts sending data online and ending when the response data has been completely received by the terminal. The transmission time depends only on the line speed.

a) 100
b) 150
c) 200
d) 250
