What is the use of virtual memory?
Virtual memory is used to increase the size of working memory in the system main memory by using the locations in secondary storage such as harddisk.
How are the best ways to increase virtual memory?
The best way to increase Virtual Memory is to increase the size of the Paging File. To do this in Windows, go to Control Panel and click on "System." Go to the Advanced tab and click the settings button under the performance section.
What is virtual memory and how the system controls the situation in the absence of it?

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.
How do you delete virtual memory?
Don't delete the virtual memory. It is essential to the running of your operating system.
What is deffernce between virtual and physical memory?
The difference between virtual and physical memory is that virtual memory refers to memory space while physical memory are chips like RAM. The memory space for virtual memory is made by operating system when there is insufficient physical memory.
When does the operating system creates virtual memory?
when the actual memory is full
What operating system doesn't use virtual memory?
As per my memory these OS Ferrodo, Linux, centos won't operate virtual memory.
The salesperson offers you a one time special 10mb of virtual memory for 100 Are you buying?
The salesperson obviously hasn't got a clue what virtual memory is - or you misunderstood him. Virtual memory is a system that is integral to the computer system, not something that can be added.
Does freeing up memory improve computer performance?
Computers operate best when they have "system memory" free and are not relying on virtual memory (which uses a hard drive as additional system memory). If you have a system with 1GB of installed system memory, and you are using 1.25GB of allocated memory, then freeing up 0.25GB of used system memory would improve performance by reducing virtual memory usage. Conversely, if you have 2.0GB of installed memory, and you are using 1.25GB of allocated memory, then freeing 0.25GB of used memory would have no appreciable effect since virtual memory is not being used by the system. Final answer: If you are using virtual memory, then freeing enough memory to eliminate the virtual memory usage will improve performance, but freeing up more than that amount will have no appreciable effect.
How much space is reserved for virtual memory on different computers?
The space reserved for virtual memory varies on different computers. It depends on the operating system in use and how much system memory is available.
Why cant you use all of your systems memory to run a virtual machine?
You can't use all of your system memory to run a virtual machine because then there wouldn't be enough memory for the Operating System that's running the virtual machine to function. For instance, if you have 4 GB of system memory total, and your operating system needs at least a quarter of that (1 GB) to function, then your virtual machine maximum memory would be 3 GB.
