Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Construct a scenario with a reference string demonstrating at least 9 page faults using fixed allocation with 3 frames, and show the replacement process.

💡 Hint: Track pages and their replacements through FIFO replacement strategy.

Challenge 2 Hard

Analyze a case where proportional allocation could lead to thrashing if processes require more memory than available.

💡 Hint: Identify maximum allocations possible versus process needs.
