Definition: zoom

(1) To make a video call. Although Skype, Facetime and other videoconferencing services preceded the application from Zoom Video Communications, Zoom became so popular that the term is used generically for any video call. See Zoom videoconferencing and videoconferencing.

(2) To change from a close-up view to a distant view (zoom out) or from a distant view to a close-up view (zoom in). An application may provide fixed or variable levels of zoom, and a graphics card may also have built-in zoom capability. All cameras have some zoom capability (see optical zoom and digital zoom). See field of view.
