Question 1.
What is Belady's Anomaly?
Show hintHide hint
Consider the implications of having more frames in memory.
Question 2.
Name one algorithm that avoids Belady's Anomaly.
Show hintHide hint
Think about the algorithms discussed in class.
3Question 3.
What does Belady's anomaly signify?
- More frames lead to fewer faults
- More frames lead to more faults
- It has no effect
Show hintHide hint
Consider the implications of frame counts.
4Question 4.
True or false: The LRU algorithm can exhibit Belady's anomaly.
- True
- False
Show hintHide hint
Think about how LRU selects which pages to keep.
Question 5.
Design a simulation that demonstrates Belady's anomaly using FIFO. Use a program to keep track of the number of faults as frames increase.
Show hintHide hint
Focus on tracking the sequence of accesses and noting when frames are replaced.
Question 6.
Create a detailed analysis comparing the fault rates of LRU and Optimal across different frame counts using specific page reference strings.
Show hintHide hint
You may use a table format to compare the results clearly.
