Question 1
What is the main goal of page replacement algorithms?
- Increase CPU speed
- Minimize page faults
- Reduce memory allocation size
💡 Hint: Think about what happens when a page is not in memory.
Question 2
True or False: The LRU algorithm guarantees the minimum number of page faults.
- True

Challenge Problems
Push your limits with challenges.
Question 1
Given a page reference string of '5, 2, 3, 5, 1, 2, 1, 5' and a memory size of 3 pages, analyze how FIFO would replace pages and calculate the total number of page faults.
💡 Hint: Keep track of the pages that are stored as they come in and note when they cause a fault.
Question 2
Evaluate the difference in performance between LRU and LFU with an access sequence of '3, 5, 2, 3, 5, 2, 1'. Calculate the faults for both algorithms.
💡 Hint: Work out each step of access for both and keep historical counts.
