Suppose a client sends a message directly to one of the servers (to server). The message is 1.25 kilobytes long.
a) If the message transmission time is 2 milliseconds, calculate the data transfer rate in kilobits per second.
b) If the server receives an acknowledgment message from the client, which is also 1.25 kilobytes long, and the acknowledgment transmission time is 1.5 milliseconds, calculate the round-trip time for the message.
