  1. Question 1

    Q1. What is the efficiency of a stop-and-wait protocol with a packet size of 1000 bytes and a bandwidth of 1 Mbps?

    • A) 0.5
    • B) 0.8
    • C) 0.2
    • D) 0.1

    Answer: 0.2

    Explanation: Efficiency = 1 / (1 + 2a), where a = propagation time / transmission time. Assuming a = 2, efficiency = 1 / 5 = 0.2.
