What is thrashing?
Think about what happens during high page faults.
What does Belady's anomaly describe?
Consider how memory pages interact when frames increase.
What is thrashing?
It occurs when memory management is inefficient.
True or False: LRU can exhibit Belady's anomaly.
Think about how LRU manages pages compared to FIFO.
Examine the following access pattern: 3, 4, 2, 1, 5, 3, 2, 1. Determine the page faults with 2, 3, and 4 frames.
Analyze the replacement priority based on the algorithm.
Given a write-heavy application, suggest a memory management strategy to mitigate thrashing while ensuring data integrity.
Think about how to balance between writing to disk and keeping active pages in RAM.
