Question 2: Given the main memory is composed of only three pages frames for public use and that a program requests pages in the following order: \[ 2,1,1,0,9,2,1,8,3,2,1,1,0,8 \] Where STUVWXY is your matric number a. Using the FIFO page removal algorithm, indicate the movement of the pages into and out of the available page. Then compute the failure and success ratios. b. Using the LRU page removal algorithm, indicate the movement of the pages into and out of the available page. Then compute the failure and success ratios. c. Using the MRU page removal algorithm, indicate the movement of the pages into and out of the available page. Then compute the failure and success ratios. d. Using the LFU page removal algorithm, indicate the movement of the pages into and out of the available page. Then compute the failure and success ratios.
