Paging and Page Replacement Algorithms in Operating Systems - 2025

Learn paging concepts and page replacement algorithms in this comprehensive video series that covers essential memory management topics in operating systems. Master fundamental paging and segmentation basics, understand how page faults occur and are handled, and explore the mechanics of thrashing in memory systems. Study key page replacement algorithms including First-In First-Out (FIFO), Optimal, Least Recently Used (LRU), Least Frequently Used (LFU), and Second Chance algorithms through detailed explanations and worked examples. Compare the performance and characteristics of different algorithms to understand their practical applications in real-world operating systems. Solve numerical problems and examples that demonstrate page fault handling scenarios and algorithm implementations. Note that this content has been integrated into a newer, more comprehensive Operating Systems course covering CPU scheduling, paging, and deadlocks for a complete learning experience.
