Question 1

What is Belady's anomaly?

  • A decrease in faults as frames increase
  • An unexpected increase in faults as frames increase
  • A consistent number of faults regardless of frames

💡 Hint: Consider why having more frames could complicate memory access.

Question 2

The FIFO page replacement algorithm...

Challenge Problems

Push your limits with challenges.

Question 1

Given a new page reference string and a varying number of frames, illustrate how page faults would change if FIFO and LRU are applied.

💡 Hint: Visualize the process to better understand changes.

Question 2

Critique the effectiveness of FIFO versus LRU under high demand scenarios, discussing potential outcomes.

💡 Hint: Use actual numbers to illustrate results of page faults for each approach.
