Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Explain how you would apply proportional allocation to a dynamically changing set of processes, incorporating priorities. What steps would you take to assess memory needs?

💡 Hint: Consider using a formula to assess and adjust allocations.

Challenge 2 Hard

A system has 200 frames. Process A needs 70 frames, Process B needs 50 frames, and Process C needs 80 frames. Describe how you would handle allocation if a new high-priority Process D requiring 60 frames starts.

💡 Hint: Think about how to balance needs without compromising performance drastically.
