yes that's the page table, with corrected indexes it looks like this: process 0: 0,1,2,3 process 1; 4,5,6,7 process 2: 99,99,99,99 process 3: 99,99,99,99 process 0 and 1 are loaded into ram with values 0-7 but now there is a new issue with instruction '0' 'the next page of process 0 has to be brought in from virtual memory to the RAM' however every page from process 0 is already loaded into RAM do I just switch the pages like so: process 0: 0,1,2,3 process 0: 1,0,2,3 (and update the time step for these 2 that change) or does something else need to happen?
