Question 1
What is the primary purpose of a page replacement algorithm?
- To keep more pages in memory
- To optimize page faults
- To track hardware performance
💡 Hint: Consider what happens when data is not located in RAM.
Question 2
True or False: The Sampled LRU algorithm reduces tracking overhead by only sampling pages periodically.
- True
- False
💡 Hint: Think about how frequently tracking can slow down performance.

Challenge Problems
Push your limits with challenges.
Question 1
Given a series of page references: 2, 0, 1, 6, 4, 2, 0, 1, 6, 4, 0, 1, 0, 3, 1, 2, 1 with 4 page frames, calculate the page fault rate for Sampled LRU.
💡 Hint: Count the number of page faults you experience and divide it by the total references.
Question 2
Compare the performance impact of using FIFO versus Sampled LRU in a heavily accessed system.
💡 Hint: Evaluate which algorithm allows more flexibility based on access patterns.
