Opposite of real or physical.virtualA condition without boundaries or constraints. The word virtual is used to define a feature or state that is simulated in some manner; for example, a "virtual world" is all computer-generated imagery.
It Started with Virtual Memory
The first virtual term was "virtual memory," in which the contents of RAM is saved to storage and swapped back and forth as needed. Virtual memory is common on every modern computer (see virtual memory).
The Virtualized Datacenter
A "virtual machine" is a computer within a computer. The driver of cloud computing technology, 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.
Online,Electronic and Internet
Having such a high-tech ring, the word virtual evolved to mean "virtually" anything (see list below). Virtual is often used as a substitute for the words "online," "computerized," "electronic" or "Internet." It has also been used to mean "not physical," for example, "The company's product will be virtual for another year."
