device:
A component attached to the computer. Internal devices are mounted on the
chassis. External devices are connected to the computer via a port.

A program that controls the operation of a specific device such as the
screen, CD-ROM drive or printer. The operating system loads many device
drivers when you turn the computer on.
diagnostic tools:

you that a process has completed successfully. Alternatively, it may be a
warning that the computer cannot do what you asked or that obeying your
instructions may destroy data. This second type of dialog box is also called a

digital:
Data expressed in discrete numerical units according to a predetermined code. In
computing, data are expressed in binary code--an electronic pulse or no pulse,
either “on” or “off.” Voice and video, which usually originate in analog form, can
be converted to digital signals. Voice is converted using pulse code modulation
(PCM) to 64 Kbit/s.
digital signal processor (DSP)
: A chip designed for high-speed data manipulation and
widely used in communications and data control applications. Sound boards
use DSPs to handle various sound formats and filters. Modems use DSPs to
handle modulation protocols.
DIMM:
Dual Inline Memory Module. A unit of RAM used for memory expansion.
DIP switch:
A set of tiny toggle switches built into a dual in-line package, which is
mounted directly on a circuit board. The switches may be rocker-style or
sliders. In both cases, the tip of a pen or pencil is required to flip the switch on
or off.
