Challenge Problems
Push your limits with advanced challenges
Explain how the VM system decides which frame to replace when a page fault occurs. Discuss the potential consequences of using FIFO vs. LRU algorithms in this context.
💡 Hint: Consider the role of the dirty bit and memory access history in these algorithms.
Considering a virtual memory system with a run of loops that sequentially access pages A, B, C, what issues would arise in a page table with poorly designed page replacement algorithms under a low physical frame limit?
💡 Hint: Think about how memory locality is impacted by frame availability and replacement policies.
