Challenge Problems

Push your limits with challenges.

Question 1

You have 6 pages in memory with reference bits: A(1), B(1), C(0), D(0), E(1), F(0). If a page fault occurs for G, which page will be replaced? Illustrate the process.

💡 Hint: Visualize the process of checking bits in a circle.

Question 2

Explain how increasing the number of frames in a system could lead to more page faults under certain conditions using FIFO versus Clock Algorithm.

💡 Hint: Consider page access patterns and how they affect fault rates.
