Challenge Problems
Push your limits with advanced challenges
Analyze a scenario where you have four pages in memory: A, B, C, and D. If pages A and B are accessed frequently and C and D are rarely used, how would you configure your reference bits for each page, and what would your replacement strategy be?
💡 Hint: Think about how often pages are actually accessed versus how long they remain in memory.
Design a simple simulation of the second chance algorithm using a small set of pages. Given pages A, B, C, and a new page D that needs to be brought into memory, demonstrate how the algorithm would process the page replacements.
💡 Hint: Follow the logical flow of replacement step-by-step, considering both the reference bit status and when to replace.
