A producer generates data faster than a consumer can process it. The buffer has a fixed capacity and eventually becomes full. What is the most appropriate general conclusion?

Options

  • A. The buffer automatically increases the consumer processing speed
  • B. The system must apply flow control, pause the producer, or handle incoming data loss
  • C. The producer can continue indefinitely without any consequence
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. The system must apply flow control, pause the producer, or handle incoming data loss

Detailed Explanation

Correct Answer: The system must apply flow control, pause the producer, or handle incoming data loss.

Explanation: A finite buffer cannot absorb a sustained rate mismatch indefinitely. When it becomes full, the system may use backpressure or flow control to slow the producer, temporarily stop production, or discard data if the application permits it. Increasing buffer size only delays overflow when the long-term production rate exceeds the consumption rate.
