virtual (jargon, architecture) (Via the technical term virtual memory, probably 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) created by a computer system to help the system control 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. Opposite of real or physical. [Jargon File] Last updated: 1994-11-30
