Answer:
B. False
Explanation:
A page-replacement policy can be defined as a set of algorithm that instructs the operating systems on what memory page is to be swapped, paged out or written to disk in order to allocate more memory as they're required by various active processes during virtual memory management.
Some of the algorithms or techniques used by the operating system for page-replacement policy are;
1. Last In First Out (LIFO).
2. First In First Out (FIFO).
3. Least Recently Used (LRU).
4. Least Frequently Used (LFU).
5. Optimal (OPT or MIN).
Hence, the page-replacement policy means that pages are placed to make more space and to minimize the total number of page that would be missing.
