Hi, if we load the page frames in sorted by page num the memory looks like this: process 1: 0,1,2,3 process 2: 4,5,6,7 process 3: 99,99,99,99 process 4: 99,99,99,99 RAM: 0,1,2,3,4,5,6,7 DISK: 99,99,99,99,99,99,99 but if we get the instruction '3' there is no process 3 in main memory to swap to, instead are we supposed to put in 2 each to avoid this? e.g. process 1: 0,1,99,99 process 2: 2,3,99,99 process 3: 4,5,99,99 process 4: 6,7,99,99 RAM: 0,1,2,3,4,5,6,7 DISK: 99,99,99,99,99,99,99,99 so now instruction 3 changes it to RAM: 0,1,2,99,4,5,6,7 DISK: 99,99,99,99,99,99,3,99 or is there a better way?
