Assume a main memory with four page frames (frame A through frame D). Assume that the sequence of pages requested by a process is as shown below.

4, 1, 7, 10, 8, 4, 8, 7, 1, 4, 7, 10, 4, 8, 4, 1, 7, 10

For each reference in the above sequence, identify whether it will cause a page fault (F) or will result in a page hit (H), when using the page replacement algorithm specified in the sub-questions. For each sub-question, use the table provided for your solutions use the Status column to indicate F or H and the Page Frame column to indicate into which page frame the page has been loaded. Assume that all page frames are initially empty.

Given the above information, complete the table presuming the we are using a First In First Out or FIFO page replacement policy:
