5 cards from this section. Quick, good the night before a test.
Define Belady's anomaly in your own words.
Think of examples of how faults behave with increased frames.
What does LRU stand for?
It relates to how memory pages are managed and accessed.
What is Belady's anomaly?
Consider scenarios in which you'd see this phenomenon.
True or False: The LRU algorithm can exhibit Belady’s anomaly.
Think back on how LRU pages are selected and replaced.
Given a sequence of page requests and four frames, evaluate the efficiency of both LRU and the Optimal algorithms. What differences do you observe in page faults?
List your page hits and faults for each frame accordingly.
Design and justify a frame allocation scheme for a varied workload environment with example scenarios for each type (fixed, proportional, and priority).
Consider applications with distinct memory needs.
