Digital may refer to any of the following:

Digital signal

1. An electronic signal that is sent as binary digits of either ON (the number one) or OFF (the number zero). In the illustration, a digital signal is the segments that are up or down for either ON or OFF and discontinuous; unlike an analog signal, which is continuous and more like a wave. This example also illustrates a digital picture where a pixel is turned either ON or OFF helping to create an image on a display.

2. Digital is also a computer company. See our Digital company page for more info about this business.
