Question 1

What does the Optimal page replacement algorithm do?

  • Replaces the oldest page
  • Replaces the least frequently used page
  • Replaces the page not needed for the longest future period

πŸ’‘ Hint: Think about its decision-making principle.

Question 2

Belady's Anomaly occurs when increased memory leads to:

  • More page faults
  • Fewer page faults

πŸ’‘ Hint: Recall examples discussing memory dynamics.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a real-time application involving multiple user requests over a short time. How would the use of the Optimal algorithm affect overall system performance and user experience?

πŸ’‘ Hint: Consider how memory management strategies differ when under time-sensitive conditions.

Question 2

Devise a scenario where memory-intensive applications alter access patterns, causing traditional algorithms like FIFO to underperform when evaluated against the Optimal paradigm.

πŸ’‘ Hint: Map out changing access patterns and how they impact memory management choices.
