4 cards from this section. Quick, good the night before a test.
What is Belady's anomaly?
Think about what happens to page faults with more frames.
Name two page replacement algorithms.
Consider popular algorithms used in operating systems.
What is Belady's anomaly?
Think about how frames relate to page faults.
True or False: LRU algorithm can experience Belady's anomaly.
Reflect on the nature of how LRU keeps track of page usage.
Given a reference string, calculate the page faults with 3 and 4 frames. Explain how the results illustrate Belady's anomaly.
Track each page reference and keep note of hits and misses.
Propose a modified version of the LRU algorithm that could potentially enhance frame efficiency.
Think about how future access might affect current page decisions.
