Challenge Problems
Push your limits with advanced challenges
Consider a system with 5 pages and a time interval where each page gets accessed. If the pages are subsequently accessed in this order: A, B, C, D, A, B, C, D, E, determine how many pages will be replaced and in what order according to both FIFO and the second-chance algorithm.
