Type of Page replacement algorithms

Question

Distinguished different type of Page replacement algorithms?

Answer 1

Page replacement: page replacement which of the pages to throw out of memory. Once all memory is in use, will require throwing out one page each time there is a page fault.

1. Random: pick any page randomly
2. FIFO: throw out the page which has been in memory for long time.
3. MIN: The optimal algorithm needs us to predict the future.
4. Least Recently Used (LRU): use the past to predict the future.
