Paging vs. Swapping

First some basic infos - based on the-mother-of-all-operating-systems by A. Tannenbaum

  • paging - individual memory pages are written to disk
  • swapping - transfer the memory of a whole process to disk

In Linux - so it seems to me - are the term often mixed. Linux is doing paging for sure, but the on disk location is called swap partition (or file). Most (all?) tools are showing the results of both types.

Solaris on the other hand - does differentiate quite a lot. Depending on the tool one can see the paging or the swapping.
