Questions tagged [virtual-memory]
Virtual memory is a method where each process is given its own address space (virtual memory), and the hardware translates every VM reference to a physical memory address. Originally VM was used to provide more address space than the available physical memory. To accommodate situations when more virtual memory is in use than physical memory, a storage device such as HDD can be used to "swap out" data and later "swap (back) in" as needed.
