`
`direct cable connection
`
`:/ ·
`
`dil"ect cable connection \ddr-ekt'
`kd-
`ka'bl
`nek'sh;m\ n. A link between the I/0 ports of
`two computers that uses a single cable rather
`than a modem or other active interface device.
`In most cases, a direct cable connection requires
`a null modem cable.
`dfrect-connect modem \d;;ir-ekfkd-nekt mo'd;;im\
`n. A modem that uses standard telephone wire
`and connectors and plugs directly into a telephone
`jack, eliminating the need for :10 imermediary tele(cid:173)
`phone. Compare acoustic coupler.
`dil"ect-coupled tt·ansistor logic \ ddr-ekt' b-pld
`tranz-i'st;;ir loj'ik\ n. A circuit design that uses
`transistors and resistors only, with the transistors
`directly connected to each other. This design was
`used in the earliest commercial integrated circuits.
`The switching speed and power consumption of
`such circuits are about average. Acronym: DCTL
`(ffC-T-L').
`direct cm·rent \ddr-ekf kur'dnt\ n. Electrical cur(cid:173)
`rent whose direction of flow does not reverse. The
`current may stop or change amplitude, but it
`always flows in the same direction. Acronym: DC
`(D-C). Compare alternating current.
`dil"ect digital colo1· proof \ ddr-ekf cl if i-tdl kd' l;;ir
`prdbf'\ n. A test sheet produced by a lower-cost
`output device, such as a color laser printer, to
`serve as an approximation of what the final image
`will look like when produced on professional(cid:173)
`quality printing equipment. A direct digital color
`proof does not involve color separation, as in tra-
`
`ditional proofs. Instead, a direct digital color proof
`is printed in all colors at one time on a single page,
`resulting in somewhat lower quality compared
`with traditional separation methods but having the
`advantages of increased speed and reduced cost.
`Acronym: DDCP (ffD-C-P'). Also called digital
`proof. See also color separation (definition 1).
`Dil"ect Gi·aphics Interface Specification
`\ ddr-
`ekt' graf iks in 'tdr-fas spes-d-fd-ka' shdn \ n. See
`DGIS.
`Dfrectlnput \d;}r-ekt' in'put\ n. An application
`programming interface for joysticks and similar
`pointing devices in Windows 95.
`direction key \ cfar-ek, sh;;in ke' \ n. See arrow key.
`db:ect 1nemory access \d;;ir-ekt' mem-dr-e ak'ses\
`11. Memo1y access that does not involve the micro(cid:173)
`processor and is frequently used for data transfer
`directly between memrny and an "intelligent"
`peripheral device, such as a disk drive. Acronym:
`DMA (ffM-A').
`directory \cl;}r-ek'tdr'e\ n. A catalog for filenames
`and other directories stored on a disk. A directory
`is a way of organizing and grouping the files so
`that the user is not overwhelmed by a long list of
`them. The topmost directory is called the root
`direct01y; the directories within a directory are
`called subdirectories. Depending on how an oper(cid:173)
`ating system supports directories, filenames in a
`directory can be viewed and ordered in various
`ways-for example, alphabetically, by elate, by
`size, or as icons in a graphical user interface.
