Advantage of virtual memory?
Virtual Memory can extend the memory available to programs when the chip-type memory is limited. Windows prefers to have Virtual memory, a lot of games are written to use more virtual memory in an attempt to save you RAM. ...
Asked in Computer Memory, Hard Disk Drives
Is a virtual memory a special chip inside the hard disk?
No. Virtual memory is a file stored on the disk and managed by the operating system software. As needed the operating system copies blocks of internal memory out to this file to free internal memory and copies blocks from this file to internal memory when a program needs it again. To assist the operating system in this task the computer has to have virtual memory management hardware and interrupts. All of the hardware that is involved directly in the operation of virtual memory is...
Asked in Software Security
A software of 2GB can run over a 512 MB of primary RAM available with the help of virtual memory.Then why is it written on the software that minimum RAM required for it is so and so?
A software which need 2GB RAM will may run with 512MB RAM [Not in a perfect way]. Today computers use virtual memory for multitasking [for running more programs at the same time]. An over-reliance upon virtual-memory can slow overall system performance. By enabling the virtual memory feature, you are asking the computer to use a part of the Hard Disk as Physical Memory [RAM]. Always remember that the Hard Disk is much slower than the original RAM. In this case, you are...
Difference between ram and virtual memory?
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. ...

Asked in Computer Hardware
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...
