Memory overcommitment.Virtual memory systems allow the allocation of more memory to applications than is physically present by using mechanisms like overcommitment and memory overallocation. These approaches are useful in environments where applications might reserve more memory than they actually use. Load ...
Virtual memory is a form of logical memory. Logical memory is read by computers as primary memory, but it exists on a local drive and isn’t directly accessed by the CPU. The computer reads the address for logical memory as though it is in the motherboard as well. However, because it’...
It provides an illusion of having more RAM than physically available, allowing for larger programs to run.How does virtual memory work?When the random access memory (RAM) is fully utilized, the operating system moves some of the less frequently used data from RAM to the hard disk drive (HD...
With virtual memory, the computer can look for areas of RAM that have not been used recently and copy them onto the hard disk. This frees up space in RAM to load the new application. Because it does this automatically, you don't even know it is happening, and it makes your computer ...

First, RAM stands for Random Access Memory. Any location of the RAM can be read or written equally fast, there is no USE for it to be contiguous with virtual memory, nor does any head seek need to be done (because it's not an HDD). There is no pre-fetching like on HDDs, it jus...
A fully or mostly virtualized environment mimics that of the cloud, getting you set up for the switch to cloud. In addition, you can choose to deploy your VMs in the cloud. How does virtualization work? One of the main reasons businesses use virtualization technology is server virtualization,...
The space used for virtual memory on a drive is known as "backing store," or "swap space." In the Windows world, it's usually implemented as a file, known as a "swap file." It's also possible to do this in Linux, but it's much more common touse a dedicated disk partition. ...
