Digital: Denoting the use of binary notation; i.e, the representation of data by
bits (1 or 0).

digital: Using discrete expressions to represent variables. Discrete: Composed
of distinct or discontinuous elements.

Digital: Pertaining to discrete or distinct finite values. As opposed to analog
or continuous quantities.  
 
Digital: A circuit, processor, or other device using a binary numeric (1 or 0)
system to represent and process information. A digital tape recorder converts
the incoming analog audio signal into a stream of ones and zeros that are stored
onto the tape. Upon playback, the series of numbers are converted back to a
analog signal. 

Digital: describes electronic technology that generates, stores, and processes
data in terms of two states: positive and non-positive. Positive is expressed or
represented by the number 1 and non-positive by the number 0. Thus, data
transmitted or stored with digital technology is expressed as a string of 0's
and 1's. Each of these state digits is referred to as a bit (and a string of
bits that a computer can address individually as a group is a byte). 

Prior to digital technology, electronic transmission was limited to analog
technology, which conveys data as electronic signals of varying frequency or
amplitude that are added to carrier waves of a given frequency. Broadcast and
phone transmission has conventionally used analog technology. Digital technology
is primarily used with new physical communications media, such as satellite and
fiber optic transmission.

Digital: <data> A description of data which is stored or transmitted as a
sequence of discrete symbols from a finite set, most commonly this means binary
data represented using electronic or electromagnetic signals. 

Digital: A form of representation in which distinct objects, or digits, are used
to stand for something in the real world, so that counting and other operations
can be performed precisely. Data represented digitally can be manipulated to
produce a calculation, a sort, or some other computation. In digital electronic
computers, two electrical states correspond to the 1’s and the 0’s of binary
numbers, which are manipulated by computer programs.
