Challenge Problems
Push your limits with advanced challenges
Imagine a system with 3 page frames. Given the request sequence A, B, C, D, A, B, C, D, E and F, determine how many page faults occur with FIFO and LRU strategies.
💡 Hint: Draw out the pages currently in memory after each request to track faults.
Discuss the trade-offs of using an LRU algorithm in a system with high memory usage.
💡 Hint: Consider the balance between performance benefits and system resource use.
