virtual: adj. [via the technical term virtual
memory, prob.: from the term virtual
image in optics] 1. Common alternative to logical; often used
to refer to the artificial objects (like addressable virtual memory larger
than physical memory) simulated by a computer system as a convenient way to
manage access to shared resources. 2. Simulated; performing the functions of something that isn't
really there. An imaginative child's doll may be a virtual playmate.
Oppose real.
