digital[dij′i təl, -it'l]
- The definition of digital is something that is or is like a finger.
An example of digital is a robotic finger.
- Digital is defined as something relating to a device that transmits information by discrete numerics.
An example of digital is an mp3 player.
- of, like, or constituting a digit, esp. a finger
- having digits
- performed with a finger
- using numbers that are digits to represent all the variables involved in calculation
- using a row of digits, rather than numbers on a dial, to provide numerical information: a digital watch, a digital thermometer
- designating or of data, images, sounds, etc. that are stored, transmitted, manipulated, or reproduced by a process using groups of electronic bits represented as 1 or 0
- of or by means of such a process, as one using a digital computer
- designating or of a recording technique in which sounds or images are converted into groups of electronic bits and stored on a magnetic or optical medium: the groups of bits are read electronically, as by a laser beam, for reproduction
- designating or of a type of radio or TV transmission and reception in which data, sounds, or images are sent or received as groups of electronic bits

digital - Computer Definition
Pertaining to the representation of data by means of digits, or discrete quantities such as numbers or signals that can be interpreted as numbers. By contrast, analog signals have meaning at all intermediate levels. In telecommunications, digital transmission systems make use of pulses or varying levels of electromagnetic energy, such as electricity, radio waves, or light. Digital communications originates in telegraphy, in which a mechanical key is used to close an electrical circuit for varying lengths of time to send a series of short pulses (dots) and long pulses (dashes) that, in specific combinations, represent specific characters or series of characters. Early mechanical computers used a similar concept for input and output. Contemporary computer systems communicate in binary mode through variations in electrical voltage. Digital signaling in a contemporary electrical transmission system involves a signal that varies in voltage to represent one of two discrete and well-defined states.Two of the simplest approaches are unipolar and bipolar signaling. Unipolar signaling makes use of a positive (+) voltage and a null, or zero (0), voltage. Bipolar signaling, makes use of a positive (+) or a negative (

(3) For centuries, digital meant the use of numbers, the term coming from digit, or finger. Today, digital is synonymous with computer. Digital Means Perfect Copies The 0s and 1s of digital data mean more than just on and off. They mean perfect copying. When information, music, voice and video are turned into binary digital form, they can be electronically manipulated, preserved and regenerated perfectly at high speed. The millionth copy of a computer file is identical to the original. While this has driven software and content publishers to distraction protecting their copyrights, it is nevertheless a major advantage of digital processing. See binary.
digital - Investment & Finance Definition
A format in which bits of data (information represented by 1s and 0s) are stored, transmitted, or manipulated. Each individual digit is a bit. Contrasts with analog format, in which data is transferred by amplifying the strength of the signal or varying its frequency in order to transmit information.
