virtual - Computer Definition
Being in essence or effect, although not in reality. A virtual circuit, for example, is not a physical circuit, but behaves as though it were, at least in some respects.Virtual is virtually the opposite of transparent, as something transparent exists but appears almost as though it does not. See also transparent, virtual Centrex, virtual circuit, virtual path, virtual WATS, and VPN.
Refers to a condition without boundaries or constraints. It is often used to define a feature or state that is simulated in some manner. The term is overused and may refer to "virtually" any hardware or software product or Internet-related service that has some advanced features. Virtual Can Mean a Lot of Things Virtual has such a high-tech ring that it is used as a substitute for the words "computerized," "electronic," "Internet" or "online." It has also been used to mean "not physical," for example, "the company's product will be virtual for another year." It Started with Virtual Memory One of the first virtual terms was "virtual memory," in which the contents of memory is saved to disk and swapped back and forth as needed. Common on every modern computing device, the memory is simulated on disk (see virtual memory). The Virtualized Datacenter A "virtual machine" is a computer within a computer. The heart of the cloud computing infrastructure, the virtual machine is an operating system that communicates with a control program and not the hardware directly. The hardware is being simulated or "virtualized" (see virtual machine). See cloud computing.
