Memory Swapping
Use of a swap file or swap partition is a way for the operating system to provide more memory than is physically available by keeping portions of the primary memory in secondary storage. While multitasking and memory swapping are two completely unrelated techniques, they are very often used together, as swapping memory allows more tasks to be loaded at the same time. Typically, a multitasking system allows another process to run when the running process hits a point where it has to wait for some portion of memory to be reloaded from secondary storage.

Famous quotes containing the words memory and/or swapping:

Devoted to the memory of me:
Then shall my ghost not walk about, but keep
Still in the cool and silent shades of sleep.”

In sunlight smiling under their goggles swapping batons back and

And He who jumped without a chute and was handed one by a diving
Buddy.”
