What is the multi-level feedback queue (MLFQ) scheduler?
Correct! Well done.
Incorrect.
The correct answer is B) A scheduler with multiple queues of decreasing priority, demoting CPU-intensive processes and promoting I/O-bound processes dynamically
B
Correct Answer
A scheduler with multiple queues of decreasing priority, demoting CPU-intensive processes and promoting I/O-bound processes dynamically
Explanation
MLFQ estimates process behavior: new processes start at high priority; if they use their quantum, they are demoted; if they yield early, they stay high. This approximates SJF without knowing burst times.
