(tco 6) consider a demand-paging system in which a process is allocated six frames. let the least recently used (lru) algorithm be employed to select pages for replacement. let the sequence of page references for the process be as follows: 1, 3, 4, 1, 5, 2, 3, 8, 6, 7, 10, 3, 9, 4, 3, 8, 5, 1, 2, 5, 3, 1, 7, 5, 1, 2 at the end of processing the above sequence of references, determine the set of pages resident in memory. now, identify the page reference from the following that will cause a page fault.
