`
`digital audio tape
`
`digital signal processor
`
`ber of bits used. Compare analog; see also digital-
`to-analog converter.
`digital audio tape Abbreviated DAT. A magnetic
`tape storage medium for recording digitally en-
`coded audio information.
`digital camera A type of camera that uses either
`the body and lens of a conventional camera (such
`as a 35mm or larger camera) or a proprietary
`body and lens and that stores the photographed
`image electronically instead of on traditional film.
`A digital camera uses a CCD (charge-coupled de-
`vice) element to capture the image through the
`lens when the operator releases the shutter in the
`camera; circuitry within the camera then stores
`the image captured by the CCD in a storage medi-
`um such as solid-state memory or a hard disk. Af-
`ter the image has been captured, most digital
`camera systems require that the camera be con-
`nected to a computer by a cable and the image
`downloaded to the computer using software sup-
`plied with the camera. Once stored in the com-
`puter, the image can be manipulated and
`processed much like the image from a scanner or
`related input device.
`digital communications Exchange of communi-
`cations in which all information is transmitted in
`binary-encoded (digital) form.
`digital computer The type of electronic device
`considered a computer by most people. A digital
`computer is one in which operations are based
`on two or more discrete states. Binary digital
`computers are based on two states, logical ON
`and OFF, represented by two voltage levels, ar-
`rangements of which are used to represent all
`types of information—numbers, letters, graphics
`symbols, and program instructions. Within such a
`computer, the states of various circuit compo-
`nents change continuously to move, operate on,
`and save this information. Compare analog
`computer.
`digital data transmission The transfer of infor-
`mation encoded as a series of bits rather than as a
`fluctuating (analog) signal in a communications
`channel.
`digital display A video display capable of ren-
`dering only a fixed number of colors or gray
`
`shades. Examples of digital displays include
`IBM's Monochrome Display, Color/Graphics Dis-
`play, and Enhanced Color Display. Compare ana-
`log display.
`digital line A communications line that carries in-
`formation only in binary-encoded (digital) form.
`To minimize distortion and noise interference, a
`digital line uses repeaters to regenerate the signal
`periodically during transmission. Compare ana-
`log line.
`digital photography The use of a digital camera
`to photograph an object. Digital photography dif-
`fers from conventional photography in that a
`digital camera does not use a silver halide–based
`film to capture an image. Instead, a digital camera
`captures and stores each image electronically,
`bypassing conventional photography require-
`ments such as film and developing. See also digi-
`tal camera.
`digital proof See direct digital color proof.
`digital recording The storage of information in
`binary-encoded (digital) format. Digital record-
`ing involves the conversion of information—text,
`graphics, sound, or pictures—to strings of l's and
`CI's that can be physically represented on a storage
`medium. In a computer, for example, a magnetic
`disk drive converts electric pulses representing
`l's and D's to magnetic flux changes in which
`magnetic particles on a disk are oriented in one
`of two possible directions. Taken together, the
`alignments of all the particles on the disk repre-
`sent digitally recorded information. Digital re-
`cording media include computer disks and tapes,
`optical (or compact) discs, and ROM cartridges of
`the type used for some software and many com-
`puter games.
`digital signal A signal, such as one transmitted
`within or between computers, in which informa-
`tion is represented by discrete states—for ex-
`ample, high voltages and low voltages—rather
`than by continuously variable levels in a continu-
`ous stream, as in an analog signal.
`digital signal processor Abbreviated DSP. An
`integrated circuit designed for high-speed data
`manipulations, used in audio, communications,

`DIP
`digital sort
`
`D]
`
`modeled object—for example, using lines, ar-
`rows, and text (that is, measurements) to indicate
`the length, height, and thickness of walls in a
`modeled room or house.
`DIN connector A multipin connector conforming
`to the specification of the German national stan-
`dards organization (Deutsch Industrie Norm).
`See the illustration. An 8-pin DIN connector is
`used as the serial port connector on the Macin-
`tosh Plus, Macintosh SE, and Macintosh II. On
`most IBM desktop PCs prior to the PS/2, 5-pin
`DIN connectors are used to connect keyboards to
`the system unit. On IBM P5/2's, 6-pin DW con-
`nectors are used to connect the keyboard and the
`pointing device.
`
`image manipulation, and other data-acquisition
`and data-control applications.
`digital sort Also called radix sort. A type of or-
`dering process in which record numbers or their
`key values are sorted digit by digit, beginning
`with the least significant (rightmost) digit in each.
`digital speech See speech synthesis.
`digital-to-analog converter A device that trans-
`lates digital data to an analog signal. An analog
`signal consists of a voltage or current that varies
`continuously within a range of values, whereas a
`signal represented as digital information consists
`of discrete numeric values in binary patterns of
`0's and l's. A digital-to-analog converter takes a
`succession of discrete digital values as input and
`creates an analog signal whose amplitude corre-
`sponds, moment by moment, to each digital
`value. See the illustration. Compact disc players
`use a digital-to-analog converter to change the
`digital data read from the disc into the analog sig-
`nal that is heard as music. Compare analog-to-
`digital converter.
`

`Digital-to-analog converter.
`digital video-interactive See DV-I.
`digitize To convert any continuously varying
`source of input, such as the lines in a drawing or
`a sound signal, into a series of discrete units rep-
`resented ( in a computer) by the binary digits 0
`and I. A drawing or photograph, for example,
`can he digitized by a scanner that converts lines
`and shading to combinations of 0's and l's by
`sensing different intensities of light and dark.
`Analog-to-digital converters are commonly used to
`perform this translation. See also aliasing, analog-
`to-digital converter.
`digitizing tablet See graphics tablet.
`dimensioning In CAD programs, a means of
`specifying and possibly controlling the measure-
`ments and spatial relationships of elements in a
`
`DIN connector.
`dingbat A small graphical element used for deco-
`rative purposes in a document. Some fonts, such
`as Zapf Dingbats, are designed to present sets of
`dingbats. The first line of the illustration shows
`the symbol equivalents of the lowercase alphabet
`in the Zapf Dingbats font, and the second line
`shows those of the uppercase letters. Compare
`bullet.

`
`diode A device that passes current in only one di-
`rection. See the illustration. A diode is usually a
`semiconductor. See also semiconductor.
`diode-transistor logic Abbreviated DTL. A type
`of circuit design that employs diodes, transistors,
`and resistors to perform logic functions.
