(gcide) | digital \dig"i*tal\ (d[i^]j"[i^]*tal), a. [L. digitals.]
1. Of or pertaining to the fingers; done with the fingers;
as, digital compression; digital examination.
[1913 Webster]
2. of or pertaining to digits[3]; expressed in digits[3], or
using digits[3]; as, a digital display; a digital clock.
[PJC]
3. (Computers) performing internal logical and arithmetic
operations by means of digits, usually represented as
binary numbers. Contrasted to analog, wherein variables
are represented as coninuous physical quantities such as
voltages or the position of a pointer on a continuous
scale; as, a digital computer.
[PJC]
Note: In digital computers, physical quantities in analog
form, such as images, sounds, distances, voltages,
etc., must first be converted to an internal digital
representation before calculations can be performed on
them. The conversion may be done by the data enterer,
by approximation, in the case of numerical values, or
by analog-to-digital conversion in the case of light or
sound intensities. The latter case uses special
equipment to convert the physical impulses into a
digital value, using a pre-defined encoding system.

digital computer
(gcide) | Computer \Com*put"er\ (k[o^]m*p[=u]t"[~e]r), n.
1. One who computes.
2. (Computers) an electronic device for performing
calculations automatically. It consists of a clock to
provide voltage pulses to synchronize the operations of
the devices within the computer, a central processing
unit, where the arithmetical and logical operations are
performed on data, a random-access memory, where the
programs and data are stored for rapid access, devices to
input data and output results, and various other
peripheral devices of widely varied function, as well as
circuitry to support the main operations.
Note: This modern sense of computer comprises the
stored-program computers, in which multiple steps in a
calculation may be stored within the computer itself as
instructions in a program, and are then executed by
the computer without further intervention of the
operator. Different types of computer are variously
called analog computer, {number cruncher,
number-cruncher}, digital computer, and {pari-mutuel
machine, totalizer, totaliser, totalizator,
totalisator}.
Syn: data processor, electronic computer, information
processing system.
[WordNet 1.5 +PJC]
3. (Computers) same as digital computer.
[PJC]digital computer \digital computer\ n.
1. (Computers) a computer that represents information by
numerical digits with a fixed number of values; -- most
commonly each piece of information is internally
represented in binary code, as an array of bits, which
are information units each of which can take only two
values. The possible values of each bit are
conventionally represented as the numbers 1 or 0.
Note: The bits of information are usually further organized,
maniplulated, and discussed as nybbles (4 bits,
rarely used), bytes (8 bits, most commonly used), or
words (from 16 to 128 bits, and in the future
probably more). A word is usually defined as the
number of bits that are processed at one time by the
central procesor unit.

glycoside, which is the essential ingredient of the
extracts of foxglove. It is a white, crystalline
