LRU Approximation
LRU approximation is a memory management technique that approximates the Least Recently Used (LRU) algorithm by periodically resetting the reference bits of pages in memory, allowing the operating system to maintain a simpler implementation while still achieving reasonable performance.
Clock Algorithm
The Clock Algorithm, also known as the Second Chance Algorithm, is a page replacement algorithm used in operating systems for managing memory. It maintains a circular list of pages in memory and gives pages a "second chance" before replacing them, considering their recent access history. While simpler to implement, it may not always make optimal replacement decisions.
