Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a system with 4 frames and a reference string of '1, 2, 3, 4, 2, 5, 1, 2, 3'. Calculate the number of page faults generated by FIFO and LRU.

💡 Hint: Trace each page allocation and monitor frame memory access.

Challenge 2 Hard

Critically analyze a scenario where using FIFO over LRU causes a drop in performance. Detail both page loads and page faults.

💡 Hint: Use a significant example with clear reference usage patterns.
