Which flow control method sends one packet and waits for an acknowledgment before sending the next?
AStop-and-Wait
BSliding Window
CMultiplexing
DRouting
Step-by-Step Solution
Solution:

  1. Step 1: Understand Stop-and-Wait flow control

    Stop-and-Wait sends one packet and waits for an acknowledgment before sending the next packet.

  2. Step 2: Compare with other methods

    Sliding Window sends multiple packets before waiting, while Multiplexing and Routing are unrelated to flow control.

  3. Final Answer:

    Stop-and-Wait -> Option A

  4. Quick Check:

    One packet at a time = Stop-and-Wait [OK]
Quick Trick: One packet then wait means Stop-and-Wait [OK]
Common Mistakes:
MISTAKES
  • Confusing Sliding Window with Stop-and-Wait
  • Thinking Multiplexing is a flow control method
  • Mixing routing with flow control
