When input-output devices operate in tandem they can function as facsimile machines with the important difference that output in digital form can be fed directly to a processor or memory. Whatever the source of the data to be written, the operator must either through program or keyboard ...
devices include the graphics input tablet, consisting of a flat sensor pad and a hand-held pointing stylus, which translates the analog motion of the pointing stylus into digitized data used to control the location of the cursor on the display screen. Still other cursor movement devices rely on...
