1 What is the advantage of sliding window flow control over stop-wait flow control?

The advantage of sliding window flow control over stop-and-wait flow control lies in its efficiency and utilization of available bandwidth. Sliding window allows multiple frames to be in transit before requiring an acknowledgment, which reduces idle time and increases throughput. In contrast, stop-and-wait requires the sender to wait for an acknowledgment after each frame, leading to potential underutilization of the communication channel, especially in high-latency networks. This makes sliding window more suitable for high-speed and long-distance communication.
