Virtual memory Paging file
Hello Dear Friends of the forum.
Having heard and read various topics concerning virtual memory, and not having enough experience in computer, can you help me understand about this:
My PC on XP Sp3 with 2 GB of DDR2 memory.
- The Virtual Memory is it essential to the smooth functioning of the PC?
- Is what we can to zero virtual memory to avoid the slowdown of PC and avoid frequent access to the hard drive?
- Does the virtual memory is used only if it runs out of memory?
- In case it is mandatory to have virtual memory, is just 1 GB?
Thank you for your help,

Yup its increase the smooth functioning of the system. And some what it is necessary.

You can remove the virtual memory. But in this case the time for the data access will be even higher.

Yes.

You can put the amount you want.

Virtual memory is a computer system technique which gives an application program the impression that it has contiguous working memory, while in fact it may be physically fragmented and may even overflow on to disk storage. Systems that use this technique make programming of large applications easier and use real physical memory (e.g. RAM) more efficiently than those without virtual memory.
Note that "virtual memory" is not just "using disk space to extend physical memory size". Extending memory is a normal consequence of using virtual memory techniques, but can be done by other means such as overlays or swapping programs and their data completely out to disk while they are inactive. The definition of "virtual memory" is based on tricking programs into thinking they are using large blocks of contiguous addresses.
All modern general-purpose computer operating systems use virtual memory techniques for ordinary applications, such as word processors, spreadsheets, multimedia players, accounting, etc.
