Consider the page reference string R={0, 1, 2, 0, 1, 2, 0, 1, 2, 3, 6, 7, 6, 7, 0, 1, 2, 3, 4} for a given process. (a) Show the memory representation of the pages using the LRU algorithm and an allocation of 3 frames. How many page faults are there? (b) Show the memory representation of the pages using the Belady Optimal algorithm and an allocation of 3 frames. How many page faults are there? (C) Show the memory representation of the pages using the working set model with a window size A=3 (A indicates the maximum number allowed for a page to be in memory before being replaced; i.e. if a page is not used for 3 consecutive times, then it must either be used/demanded next, or it has to be removed). How many page faults are there?
