This policy simply eliminates pages in the order they arrived in the main memory. By using this policy we simply remove a page based upon the time of its arrival in the memory. For instance if we comprise the reference string that is: 1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5 and 3 frames (3 pages can be in memory at a time per process) after that we have 9 page faults as shown

The optimal replacement policy, called OPT, is to evict the page which will be accessed farthest into the future. Since we can't predict the future precisely, we can't implement OP
