(1) An assembly language instruction that copies data from one location to another. See move and machine instruction.

(2) (MOVie) A QuickTime video file extension. See QuickTime.

(3) (Metal Oxide Varistor) A discrete electronic component that is commonly used to divert excess voltage to the ground and/or neutral lines. Acting like a pressure relief value, an MOV is made of zinc oxide with small quantities of bismuth, cobalt, manganese and other metal oxides. The MOV was introduced in Japan in the late 1960s and was also developed by GE in the 1970s.

One of the major problems with MOVs is that the more they receive surges, the more they wear out, and there is no warning that the components are failing. See surge suppression.
