Challenge Problems
Push your limits with advanced challenges
You have 4 physical page frames and a sequence of page accesses: A, B, C, D, A, B, E, F, C, D. Determine the page fault counts for FIFO and LRU strategies.
💡 Hint: Track which pages are in memory and replace based on each algorithm’s rules.
Analyze a scenario with mixed usage patterns in memory - a workload with excessive dirty pages. Discuss how this might affect performance based on page replacement strategies.
💡 Hint: Consider how often pages must be written and how it affects overall operations.
