Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a detailed flowchart that illustrates how the Modified Clock Algorithm determines which page to replace in case of a page fault.

💡 Hint: Start with the initial state and progress through check points for each reference bit.

Challenge 2 Hard

Evaluate a specific instance where an operating system applied the Modified Clock Algorithm and measured performance improvements. Report on the results.

💡 Hint: Consider aspects such as system running speed and efficiency.
