digit-, digiti-

(Latin: finger, toe; from Greek daktylos)

bidigitate, bidigital
Having two digits, fingers, or finger-like processes.
binary digit
A character used with computers to represent one of the two digits; either 0 or 1, in the binary number system.
1. A finger or toe in human beings or the corresponding part in other vertebrates.
2. Any of the Arabic numerals 0 to 9; one of the elements that collectively form a system of numbers.
3. Any of the symbols of other number systems, as 0 or 1 in the binary.
4. The width of a finger used as a unit of length, equal to approximately 2 cm (3/4 in).
5. In astronomy, the twelfth part of the sun's or moon's diameter; used to express the magnitude of an eclipse.

In anatomy, a jointed body part at the end of the limbs of many vertebrates.

The limbs of primates end in five digits, while the limbs of horses end in a single digit which terminates in a hoof.

The fingers and toes are digits in humans.

digital (adjective) (not comparable)
1. Pertaining to, resembling, or using a digit or digits: Nancy's computer had a digital keyboard to write emails to her sister.
2. Resembling an impression made by a finger: A digital fingerprint was made for Sam's passport.
3. Pertaining to data in the form of discrete states as contrasted to analog data in the form of continuously variable physical quantities.

In computer science, representing or operating on data or information in numerical form.

A digital clock uses a series of changing digits to represent time at discrete intervals; for example, every second.

Modern computers rely on digital processing techniques, in which both data and the instructions for manipulating data are represented as binary numbers.

digital arteries
Arteries in the hand and foot that supply the fingers and toes.
digital audio
A reference to the reproduction and transmission of sound stored in a digital format.

This includes CDs as well as any sound files stored on a computer. In contrast, the telephone system (but not ISDN) is based on an analog representation (system that represents changing values as continuously variable physical quantities) of sound.

In sound recording and reproduction systems, digital audio refers to a digital representation of the audio waveform for processing, storage or transmission. When analog sound waves are stored in digital form, each digital audio file can be decomposed into a series of samples.

digital clock
A clock that displays the time in numerical digits rather than by hands on a dial.
digital computer (s) (noun), digital computer (pl)
1. A computer that performs calculations and logical operations with quantities represented as digits, usually in the binary number system.
2. A device capable of accepting data in the form of facts and figures, manipulating them in a prescribed way, and supplying the results of these processes as meaningful information.

This device usually consists of input and output devices, storage, arithmetic and logic units, and a control unit. Usually an automatic, stored-program machine is implied.

digital display
A display that gives the information in the form of characters (numbers or letters).
digital divide
The difference in opportunities available to people who have access to modern information technology and those who do not.

A term coined by former Assistant Secretary of Commerce for Telecommunication and Communication, Larry Irving, Jr., to focus public awareness on the gap in access to information resources and services between those with the means to purchase the computer hardware and software necessary to connect to the internet and low-income families and communities who cannot afford network access.

digital satellite system (DSS)
A system in which a satellite dish receives a digital signal, decodes the signal, and passes it to a television, radio receiver, or computer.

DSS's are expected to become more important as the TV and computer converge into a single medium for information and entertainment.

digital scanner
1. An electronic device that generates a digital representation of an image for data input to a computer.
2. An optical device that reads a printed page or transparency and converts it into a graphics image for a computer.

The scanner does not recognize, nor differentiate, in any manner the content of the material it is scanning. Everything is converted into a bitmapped image, which is a pattern of dots.

digitalgia (s) (noun) (no pl)
Agony in a digit, such as a finger or a toe: Arthritis, an injury, or a cyst can all be causes for digitalgia affecting a person's finger or toe.
digitalgia paresthetica (s) (noun), digitalgia parestheticas (pl)
Pain and numbness which is usually restricted to the distribution of a single digital nerve: If Mary lifts her left arm above her head, she notices a bit of digitalgia parenthetic in her left hand as she experiences numbness in her left thumb.

A reference to the form of the corolla of the fox-glove.

Cross references directly, or indirectly, involving the "toes" and "fingers": dactylo-; hallu-; phalang-.
