d) Suppose there are four processes in the ready queue: P1, P2, P3, and P4. For each process, the CPU burst time and priority are given below. Suppose lower numbers represent high priority and there is no I/O operation involved in these processes. Show how these four processes are dispatched using a Priority Scheduling algorithm. AND identify one key problem with this scheduling algorithm. Process Burst Time Priority 1 15 2 2 7 1 3 2 4 4 10 3 e) Suppose that there are 3 free page frames (1, 2, 3) and 5 virtual pages named as A, B, C, D, E. Given the page reference stream as: AB CAD ABEBA Show the page replacement sequence using the LRU Page Replacement algorithm. f) A process has 4 pages and its page table is shown below. Assume that each page is 4KB in size. The instruction currently being executed is to load data from location 0x02101 (logical address). Where is the data located in physical memory? AND explain this page address translation process. Page index Frame no (in hex) 0 1B 1 none 2 A1 3 10
