Question 3 8.75/10.0 points (graded) There are 4 processe and three partitions in the physical memory of a system. Size of the processes and partitions are shown in the picture. The system supports variable size partitioning. Processes that needs to be loaded: Partition 1 Size = 50 KB P1 (27 KB) P2 (22 KB) P3 (36 KB) P4 (7 KB) Partition 2 Size = 35 KB Partition 3 Size = 100 KB Using First Fit technique, find out which process will be stored to which partition [ Enter the Partition number only. If any process can not be loaded in any of the partitions, enter 0.] Process P1 will be stored in Partition Number : 1 Answer: 1 1 Process P2 will be stored in Partition Number : 1 Answer: 1 1 Process P3 will be stored in Partition Number : 3 Answer: 3 3 Process P4 will be stored in Partition Number : 2 Answer: 2 2 Will there be any external fragmentation? Yes O No Will there be any internal fragmentation? (consider that an empty space greater than 2KB is not negligible in this scenario). O Yes O No Which partitions in this memory mapping will be completely free after following the first fit technique? Partition 1 Partition 2 Partition 3 None Suppose, there are 4 processes in a system - P1(17 KB), P2(14 KB), P3(30 KB) and P4(25 KB). The page size in the system is 5 KB. There are 10 KB common portions among these processes. You want to optimize the memory allocation and so you will follow the shared page concept. How many frames do you need in total to load all these four processes into the memory? 3 X Answer: 12 Page 6 T 6 + 3
