An operating system technique for providing more addressable storage to programs than is actually available on the hardware.
Storage space that may be viewed as addressable main storage, but is actually auxiliary storage (usually peripheral mass storage) mapped into real addresses; amount of visual storage is limited by the addressing scheme of the computer.
The storage space that may be regarded as addressable main storage by the user of a computer system in which virtual addresses are mapped into real addresses.
A feature that makes a computer appear to have a much larger memory than its real memory. This is accomplished by software that moves pages rapidly in and out of a high-speed, random-access storage device, usually a disk.
(computer science) memory created by using the hard disk to simulate additional random-access memory; the addressable storage space available to the user of a computer system in which virtual addresses are mapped into real addresses
external storage of large programs; contents are lost when the power is lost
Synonym for virtual memory.
A technique by which an operating system, such as VM, can make a limited amount of memory appear to be a much larger amount. The operating system divides each program into "pages," which are uniformly sized sections of the program, usually 4096 bytes in size. The active pages, those containing instructions and data that is currently in use, are kept in real memory. The inactive pages are written to a direct access storage device until the program needs to access either the instructions or data on one of those pages. When this occurs, the required page is copied back into real memory.
