Daisy Chain:- A method of connecting devices on a bus. On a daisy chained bus,
devices not requesting a signal respond to it by passing it on.
Data Bus:- An electronic pathway which carries pulses of electricity to and from the
various integrated circuits and components inside a computer. Newer PC's use
32-bit buses.
Data File:- A disk file containing the work created with an application program.
Data Type:- The attribute of a variable or field in a spreadsheet or database that
determines what kind of information it can hold. For example, text field types allow
alphanumeric information to be stored, while number data types only allow numbers
to be stored.
Database:- A computer program used to track information such as wedding invites,
income and expenses, or names and addresses of clients.
Database Producer:- An individual or organization that creates and maintains a
database.
Database Vendor:- An individual or organization that provides on-line database
searching services. A vendor may provide access to one or more databases.

Default Button:- In some dialog boxes, the command button that is selected
automatically if you press Enter or Return. In most graphical user interfaces (GUIs)
default buttons have a bold border around them.
Defrag:- A process by which files are regrouped into adjacent clusters. Your hard
drive can read and write defragmented files faster than it can files that are
fragmented.
Degauss:- On monitors, a process that demagnetizes the metal components in the
CRT which eliminates image distortion that can result from magnetic charges
acquired by the components.
Delimited Text File:- An ASCII file containing values separated by commas, tabs,
semicolons, or other characters.
Desktop:- The term for the screen background in a Graphical User Interfaces (GUIs)
on which windows, icons, and dialog boxes appear.

graphics, and page layout programs to produce publication quality documents.
Device:- A component of the system's hardware, such as a modem, printer, mouse,
sound card, or disk drive.
Device Driver:- A software program or file that links your computer with devices
such as a mouse, CD-ROM, video card, and sound card.
Dial-up Connection:- A connection to the Internet via phone and modem.
Dialog Box:- A small window that appears temporarily to request information or to
alert you to a condition. Dialog boxes usually request a response such as OK to
continue or Cancel to stop an operation.
Digital:- Composed of or employing discrete, binary representations of information.
DIMM:- Dual Inline Memory Module. A type of RAM unit used in newer computers.
DIMMs support a wider data path than SIMMs, allowing faster memory access.

available or is disabled. Also sometimes referred to as grayed out.
DIP Chip:- Dual In-line Package Chip, an old style chip.
DIP Switch:- Dual In-line Package Switch. Small on-off switches mounted in
computer hardware for purposes of user configuration.
Direct Connection:- A connection made directly to the Internet - much faster than a
dial-up connection.
Direction Keys:- Also called Arrow Keys. Keys used at times to navigate around the
screen, especially in text areas. Direction keys have arrows pointing up, down, right,
and left.
Directory:- Also called folder. A collection of files in a specific location on your disk.
Disk:- The computer media used to store information.
Disk Cache:- A portion of RAM set aside for temporarily holding information read
from a disk. It often makes data retrieval faster.
Disk Drive:- The mechanism that holds and spins a disk, reading and writing data
to it.
Disk Capacity:- The storage capacity of a floppy disk or hard disk. This is usually
measured in Megabytes (MBs) or Gigabytes (GBs).
Disk Controller:- A circuit board which provides primary control for hard or floppy
disks. The newer computers have this built into the mother board.
Disk Drive:- A hardware device that reads information from and writes information
onto disks.
Display Adaptor:- Hardware that converts information in video memory to video
output.
Dithered Color:- A color produced by a pattern of differently colored dots that
simulate the desired color.
DLL (Dynamic Link Library):- A special type of Windows program containing
functions that other programs can call.
DMA (Direct Memory Access):- A technique that some hardware devices use to
transfer data to or from memory directly without requiring the involvement of the CPU.
Document:- A data file created with a word processor. Whatever you create with an
application, including information you type, edit, view, or save.
Document Window:- In most Graphical User Interfaces (GUIs), a window within an
application window. There can be more than one document window open at a time.
Documentation:- The manual of instructions for a piece of hardware or software.
Domain Aggregate Function:- Functions used when calculating statistics over a
certain set of records (domain).
Domain:- The Internet is divided into named groups, based around a hierarchy,
called domains. Each group on the Internet has a domain.
Domain Name:- Pointer that allows you to reference Internet sites without knowing
the true numerical address.
Domain Name Service (DNS):- A distributed Internet application that translates
human friendly domain(*) names into computer friendly IP addresses(*) and vice
versa.
DOS:- Disk Operating System. A program for controlling the use and storage of
information on a disk.
DOS Prompt:- The string of characters that marks the place on the screen where
you type the next command. It usually looks something like A> or C>.
Dot Matrix Printer:- A printer in which individual letters and pictures are made up of
a series of tiny ink dots. The dots are formed by punching a ribbon with the ends of
tiny wires.
Dots Per Inch:- The resolution measurement of a monitor or printer output. It is the
number of dots per linear inch.

electrical signals very quickly. DSPs are used for a variety of devices in personal
computers, including high-speed modems and multimedia sound boards.
Dual-Scan Display:- A variant of a passive matrix display in which the top and
bottom half of the screen are refreshed simultaneously, allowing the screen to be
refreshed twice as fast, yielding better display quality.
Duplex:- Communications between computers which features data transmissions
in both directions. Full duplex allows transmission of data in both directions at the
same time. Half duplex allows transmission of data in both directions, but never at
the same time.
