swapping ==>
swap
<operating system> To move a program from fast-access memory to a
slow-access memory ("swap out"), or vice versa ("swap in"). The term often
refers specifically to the use of a hard disk (or a swap file) as virtual memory
or "swap space".
When a program is to be executed, possibly as determined by a scheduler, it is
swapped into core for processing; when it can no longer continue executing for
some reason, or the scheduler decides its time slice has expired, it is swapped
out again.
This contrasts with "paging" systems in which only parts of a program's memory
is transfered.
