Digital - (1) Any kind of
information (speech, pictures, text, etc.) that can be scanned and
transformed into binary digits. (2) A way of storing,
converting, and transmitting data in the form of binary numbers (1s and
data must be digitized (turned into digital data) before computers can
do anything with it. Basically it refers to information in a
discrete, rather than continuous (analog) form. For example, a digital
telephone transmits and receives voice information as a stream of bits.
The standard phone that we're used to are different, they're analog and
receive their data in the form of waves.
