Question 1.
What does FIFO stand for in page replacement algorithms?
Show hintHide hint
Think about the order pages are accessed.
Question 2.
What is a page fault?
Show hintHide hint
Consider what happens during memory access.
3Question 3.
What is the default page replacement algorithm used in many systems?
- FIFO
- LRU
- Optimal
Show hintHide hint
Remember the most basic algorithm.
4Question 4.
Is the Reference Bit Technique a precise implementation of LRU?
- True
- False
Show hintHide hint
Think about its purpose.
Question 5.
Given the reference string '2 0 1 6 4 2 0 1 6 4 0 1 0 3 1 2 1', explain step-by-step how each page replacement algorithm (FIFO, Optimal, LRU) would handle each access.
Show hintHide hint
Go through each reference one by one.
Question 6.
Critically analyze the implications of using the Reference Bit technique in a system with frequent memory access. What are the potential downsides?
Show hintHide hint
Consider how memory is accessed frequently.
