In this video, we explore the Least Recently Used (LRU) Page Replacement Algorithm, a widely-used technique in operating systems for managing memory. LRU replaces the page that has not been used for the longest time, making it an effective and practical strategy in many real-world systems.

Key Topics Covered:

What is the Least Recently Used (LRU) algorithm?
How LRU works to manage virtual memory
Step-by-step example of LRU in action
Benefits and limitations of LRU
Comparison with FIFO, Optimal, and other page replacement algorithms
Whether you're a computer science student or a professional in tech, this video will give you a solid understanding of how LRU helps optimize system performance by minimizing page faults.

#PageReplacementAlgorithms
In an operating system that uses paging for memory management, a page replacement algorithm is needed to decide which page needs to be replaced when new page comes in.

Page Fault – A page fault happens when a running program accesses a memory page that is mapped into the virtual address space, but not loaded in physical memory.

Since actual physical memory is much smaller than virtual memory, page faults happen. In case of page fault, Operating System might have to replace one of the existing pages with the newly needed page. Different page replacement algorithms suggest different ways to decide which page to replace. The target for all algorithms is to reduce the number of page faults.
