Selling one security and buying a similar one at almost the same time to take a loss, usually for tax purposes
Writing a suspended process' modified (dirty) pages to swap space, and putting the clean pages on the free list Swapping occurs when the number of pages on the free list falls below a specific threshold

Another method of managing memory Entire processes are swapped as needed to keep the active processes in memory Swapping can add delays if large processes are swapped frequently
A technique that the UNIX kernel uses to clean up physical memory The kernel moves entire processes from memory to disk and then reassigns the memory to some other function Processes that have been idle for more than a certain period may be removed from memory to save space Swapping is also used to satisfy extreme memory shortages When the system is extremely short of memory, active processes may be "swapped out "
An {operating system} is often able to run programs that require more memory than is physically available on the host system In order to do this, the full memory required is broken into smaller pieces, which are swapped in when required, and swapped out to disk when the space they occupy is required
Swapping occurs in the CPU when the internal memory is not large enough to store more than one application program at a time Therefore, in order to process more than one job at a time, one active job is temporarily removed from internal storage and saved on the disk while the other job processes in the area formerly occupied by the first job Swapping allows the computer to think it has more memory available than it really does, but it also results in slower processing of data
