What does FIFO stand for?
Think of how a queue operates.
Define a page fault.
Consider the consequences of accessing a page not in RAM.
What does FIFO stand for?
It relates to queue behavior.
Is the Optimal Replacement algorithm practical for real implementations?
Consider the feasibility of foreseeing future memory accesses.
Given a reference string '1 2 3 4 1 2 5 1 2 3 4 5' with a memory size of 3 pages, calculate the page fault rate for FIFO and LRU.
Track memory state during each access and count the faults.
Discuss the benefits and drawbacks of using approximations of LRU in real systems.
Compare their performance in different scenarios.
