Test Series Question on Second Chance page Replacement
Demand paging uses a second chance page replacement policy (clock). It uses one use bit to give every page one more chance in FIFO replacement. Whenever a page is referenced its use bit set to 0. Whenever it is need to replace by other page for ... 0, 1, 2, 0, 3, 0, 4, 2, 3 The number of page faults occur using clock algorithm are ___________.

Operating System Demand Paging
In a demand-paged system, it takes 100 nanoseconds to access memory. The page table has 8 entries and is held in registers. It takes 10 milliseconds to service a page fault if an empty frame is available or if the victim frame is not ... is dirty 80% of the time, find the maximum page fault rate for which the effective memory access time remains within 200 nanoseconds
