My point is not that, what OS will guess about which data should be placed temporarily to disk.
As Mark in his last post said,
It's a question of OS paging, aka virtual memory. You computer can take some of the data in RAM and write it to disk, temporarily. (This is, of course, the data the OS has determined will be least needed in the near future.)
In the BOLD lines above in his quote,He sures that OS will be using
Least Frequently Used Algorithm.Well as far as i know it depends which data OS will place temporarily in disk.It may place,
1: The data which is used just recently.
2: The data which will be not used frequently(in future)
3: The data which is used heavily.
