How does the sliding window protocol improve efficiency compared to stop-and-wait in high latency networks?

hard📝 Application Q9 of 15

Computer Networks - Physical and Data Link Layer

ABy reducing the frame size to speed up transmission

BBy allowing multiple frames to be sent before waiting for acknowledgments

CBy increasing the timeout interval for acknowledgments

DBy compressing data before sending

Step-by-Step Solution

Solution:

Step 1: Compare stop-and-wait and sliding window
Stop-and-wait sends one frame and waits; sliding window sends multiple frames.
Step 2: Understand effect on high latency
Sending multiple frames keeps the link busy, improving efficiency despite delays.
Final Answer:
By allowing multiple frames to be sent before waiting for acknowledgments -> Option B
Quick Check:
Sliding window sends multiple frames for efficiency [OK]

Quick Trick: Multiple frames sent before ACK improves efficiency [OK]
