Os Memory Management Questions
The role of the page replacement algorithm in virtual memory management is to select which pages should be evicted from the main memory when it becomes full and a new page needs to be brought in. The algorithm aims to minimize the number of page faults and optimize the utilization of the available memory. Various page replacement algorithms, such as FIFO (First-In-First-Out), LRU (Least Recently Used), and Optimal, are used to determine which pages should be replaced based on different criteria.
