virtual storage
VS. (1) Storage space that may be regarded as addressable main storage by the user of a
computer system in which virtual addresses are mapped to real addresses. The size of virtual
storage is limited by the addressing scheme of the computer system and by the amount of
auxiliary storage available, not by the number of main storage locations. (2) Addressable space
that is apparent to the user as processor storage space, from which the instructions and the data
are mapped to the processor storage locations (A, D, I).
volt
A measure of the difference in electrical potential between two points in a conductor, equal to
one ohm resistance carrying a constant current of one ampere, with a power dissipation of one
watt (D). See volts alternating current; volts direct current.
volts alternating current
VAC. A term for classifying the system in which volts exist. VAC means that the volts exist in
a circuit where the electricity can travel in either direction. Contrast with volts direct current.
See volt.
