Not exactly sure what you are asking here. Unix and Linux use virtual
memory which consists of physical memory and swap space. If a running
program is not using parts of its running image it may be moved to the
swap space, the exact implementation depends on the version of Linux or
Unix which you are running.
If a running program is actively using more memory than physical memory
available, paging (ie the movement of portions of code and data between
physical memory and swap space) will occur. The more the deficit, the
greater the impact as the operating system spends lots of its time
shuffling memory.
