Most Recently Used
Full Form of MRU
What is MRU?
Most Recently Used (MRU) is a page replacement algorithm used in operating systems to manage memory efficiently. In MRU, the page that has been accessed most recently is the first to be evicted when a new page needs to be loaded. This contrasts with the Least Recently Used (LRU) algorithm, which removes the oldest accessed page. MRU is particularly effective in scenarios where the most recently used pages are unlikely to be needed again soon, such as in certain cache configurations or when dealing with sequential access patterns. In India, MRU is a key topic in computer science curricula, especially for competitive exams like GATE (Graduate Aptitude Test in Engineering) and UGC NET (National Eligibility Test). Students preparing for these exams must understand its working, advantages, and differences from other algorithms like LRU, FIFO, and Optimal Replacement. The algorithm is implemented in hardware and software to optimize cache performance and minimize page faults. MRU's relevance extends to real-world applications in database management systems and web browsers where memory management is critical.
