What is paging in an operating system?
Paging in an operating system is part of the operation of virtual memory. Physical pages of memory are being swapped back and forth for virtual pages of memory in a file on the hard disk. This swapping allows all programs to see the same memory structure (e.g. program loads at the same fixed virtual address in memory) and allows the machine to run as if it had more memory than it really does (but at a small speed penalty). Programs and utilities that are idle may stay loaded and ready to run, but paged out of physical memory until actually needed.
How virtual address is translated into physical address?
MMU-memory management unit

How can you prevent a specific application in Windows from being relegated to virtual memory?
YOU CAN'T! Virtual memory is a system that is always in use and cannot be disabled. It is not the pagefile and it is not an extension of physical memory. Applications use virtual memory exclusively and never access RAM directly.
Difference between virtual memory and RAM?
Answer(Techsupport)Resolution: RAM and virtual memory are two different things. Virtual memory allows you to use a portion of your hard drive as though it were RAM. Your hard drive is up to 100 times slower than RAM, so virtual memory is much slower than RAM. When you upgrade your RAM, you can reduce or eliminate the use of virtual memory. Upgrading RAM makes memory available to complete tasks previously handled by virtual memory.
Is cache memory equal to virtual memory?
No! ; Cache memory is integrated in the CPU. Virtual memory is a part of the hard drive that the OS use as ram memory, when running out of real ram memory.
What is virtual memory on an Apple product?
The virtual memory on an Apple computer varies between machine and user. While virtual memory can be useful, it can also cause your computer to run more slowly. By default, other Apple devices such as the iPhone and iPod, do not use virtual memory.
Does virtual memory use available ram?
Yes!
If you buy a solid state hard drive does your computer use it as memory too?

What memory allows you to use more memory than is physically available on your computer?

How do you read virtual memory?
Find a virtual psychic to read your virtual memory.
What happens if you have no virtual memory?
If you are using a modern version of Windows (Windows 95 or latter) you will be using virtual memory. Virtual memory is NOT the pagefile and it is not an extension to physical RAM but a system that is completely integrated into the system. Applications access virtual memory exclusively, no exceptions, ever. You can not disable virtual memory. You can disable the pagefile (not recommended) but this will not disable virtual memory. The system provides a virtual environment to processes that is completely independent of how much RAM is in the system. This is an advanced system that provides many important advantages to applications and users.
