(Latin: finger, toe; from Greek daktylos)
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.
2. Resembling an impression made by a finger.
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.
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.
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.
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.
DSS's are expected to become more important as the TV and computer converge into a single medium for information and entertainment.
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.
