Understanding Page Replacement in Operating Systems
Page replacement is a critical concept in operating systems, where memory management plays a vital role. In this process, pages are brought into and out of the main memory based on demand, leading to scenarios like page faults and eviction. Various strategies such as FIFO, LRU, and NRU are employed

Understanding LRU Competitiveness Theorem
The Lemma states that if a page is ejected by the LRU algorithm after being touched in a request sequence, there is a fault in the offline algorithm. The Theorem extends this to show that for any segment where LRU incurs k faults, the offline algorithm also has a fault. The proof involves examining
