Virtual Memory Management
(Deitel, Deitel, & Choffnes, 2004)
A page replacement strategy is used to determine which page to swap when the main memory is full. There are several page replacement strategies discussed in this book, these methods are known as Random, First-In-First-Out, Least-Recently-Used, Least-Frequently-Used and Not-Used-Recently. The Random strategy randomly selects a page in main memory for replacement, this is fast but can cause overhead if it selects a frequently used page. FIFO removes the page that has been in the memory the longest. LRU removes the page that has been least recently accessed, this is more efficient than FIFO but causes more system overhead. LFU replaces pages based on…
