Question 4 Explanation:
A Page replacement algorithm is an algorithm that decides which pages should be written to disk or file, when a new page needs to be allocated.
Page replacement happens when a requested page is not in memory (page fault) and a free page cannot be used to satisfy the allocation, either because there are none, or because the number of free pages is lower than some threshold.
FIFO,LRU and optimal are examples of Page replacement algorithms
Critical section is a program section that once begin must complete execution before another processor accesses the same shared resource.
