FIFO

In which one of the following page replacement algorithms it is possible for the page fault rate to increase even when the number of allocated frames increases?

Consider a main memory with five page frames and the following sequence of page references: 3, 8, 2, 3, 9, 1, 6, 3, 8, 9, 3, 6, 2, 1, 3. Which one of the following is true with res...

A computer has twenty physical page frames which contain pages numbered $$101$$ through $$120.$$ Now a program accesses the pages numbered $$1, 2, …, 100$$ in that order, and repea...

Consider the virtual page reference string $$$1,2,3,2,4,1,3,2,4,1$$$ On a demand paged virtual memory system running on a computer system that has main memory size of $$3$$ page fr...

A system uses FIFO policy for page replacement. It has $$4$$ pages frames with no pages loaded to begin with. The system first accesses $$100$$ distinct pages in some order and the...

In which one of the following page replacement policies, Belady’s anomaly may occur?

A virtual memory system uses First In First Out (FIFO) page replacement policy and allocates a fixed number of frames to a process. Consider the following statements: $$P:$$ Increa...

Consider a virtual memory system with $$FIFO$$ page replacement policy. For an arbitrary page access pattern, increasing the number of page frames in main memory will

A memory page containing a heavily used variable that was initialized very early and is in constant use is removed when

The following page addresses, in the given sequence, were generated by a program: 1 2 3 4 1 3 5 2 1 5 4 3 2 3 This program is run on a demand paged virtual memory system, with main...

Which page replacement policy sometimes leads to more page faults when size of memory is increased?
