The purpose of a virtual hard drive is to allow multiple operating systems to be on one machine. There are a number of benefits of having a virtual hard drive such as for backup and restore is one of the systems is infected with a virus or the accidental deletion of a specific file.
You can use it for virtual memory,but you need memory still.
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.
It's called virtual memory.
virtual memory.
It can use either: real hard drives and virtual ones.
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.
No, Depending on what processor you have and how much ram you have can depend how fast your computer is. also a hard drive RPM speed as well.Edit: Windows 7 has a feature called ReadyBoost that can increase your RAM by using a USB Flash drive. It only works if your computer would benefit from its use (e.g. you are using a lot of virtual memory, and your hard drive is slower than the USB port). When ReadyBoost is operational, it will increase the speed of your computer by reducing hard drive virtual memory swapping. So the answer is actually "maybe."
If you mean you to use a virtual drive like a CD drive, then you have to use special utility (Alcohol 52%, Alcohol 100%, Power Iso, Ultra Iso, Nero and so on).
When your PC runs of of physical memory - it uses the hard drive as memory so it's much slower when it gets to that point.
I would like to have an external hard drive to store our recorded videos. Is that possible?
If by memory you mean RAM then you might be able to boot into a live CD and then perhaps use virtual memory from a hard drive?
If your computer runs out of ram it will use virtual memory, essentially meaning it will borrow space from the hard drive.
