Think about which method yields better efficiency.
Given a sequence of page requests and a FIFO strategy, identify the total page faults with 3 frames versus 4 frames.
Keep track of how many frames are filled and what keeps getting evicted.
How would using an optimal algorithm analyze the page requests differently than a LIFO approach?
Consider how future knowledge changes your decision-making.
