Show hintHide hint
Think about the order of arrival.
Question 2.
What is a page fault?
Show hintHide hint
Consider memory access patterns.
3Question 3.
What does LRU stand for?
- Last Recently Used
- Least Recently Used

4Question 4.
Is the FIFO algorithm an optimal choice for all memory access patterns?
- True
- False
Show hintHide hint
Consider whether age or usage matters.
Question 5.
Given a complex reference string in a system with 5 pages, analyze the page fault rates across FIFO, LRU, and the Clock Algorithm, then compare their effectiveness.
Show hintHide hint
Use examples for reference strings like 2, 0, 1, 6, with 5 pages.
Question 6.
Simulate a situation where all pages are dirty using the Modified Clock Algorithm. Discuss how decision-making differs when evicting pages.
Show hintHide hint
Reflect on the implications of modified pages.
