 VIRTUAL MEMORY Definition
We define VIRTUAL MEMORY |
VIRTUAL MEMORY - A section of a hard drive used to augment a computer's RAM, or main memory. Different operating systems have different ways of dealing with virtual memory. UNIX and Linux often use a separate hard drive partition dedicated to virtual memory, while Windows uses a file or files on any number of hard drive partitions. However, Linux and UNIX can be configured to use a swap file as needed also. Virtual memory is used when the operating system runs low on physical memory. Virtual memory is also used to swap out lesser used portions of physical memory, freeing it up for other operations. |
