Challenge Problems

Push your limits with challenges.

Question 1

Suppose you have a system with limited physical memory, and a process has a working set that requires more memory than what’s available. Design a strategy outlining the steps to alleviate the thrashing phenomenon.

💡 Hint: Think practically about managing both memory allocations and the priorities of processes.

Question 2

A computer program utilizes a page replacement algorithm that often leads to high page fault rates. Analyze why this may happen and propose alternative algorithms that could improve overall efficiency.

💡 Hint: Consider how frequently accessed pages correlate with efficiency.
