What is the primary purpose of a page replacement algorithm?
💡 Hint: Consider what happens when data is not located in RAM.
True or False: The Sampled LRU algorithm reduces tracking overhead by only sampling pages periodically.
💡 Hint: Think about how frequently tracking can slow down performance.

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.
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.
