DDR SDRAM
— double-data-rate SDRAM — A type of SDRAM that doubles the
data burst cycle, improving system performance.
DDR2 SDRAM
— double-data-rate 2 SDRAM — A type of DDR SDRAM that uses a
4-bit prefetch and other architectural changes to boost memory speed to over 400 MHz.
device
— Hardware such as a disk drive, printer, or keyboard that is installed in or
connected to your computer.
device driver
— See
driver
.
DIMM
— dual in-line memory module — A circuit board with memory chips that
connects to a memory module on the system board.
DIN connector
— A round, six-pin connector that conforms to DIN (Deutsche
Industrie-Norm) standards; it is typically used to connect PS/2 keyboard or mouse
cable connectors.
disk striping
— A technique for spreading data over multiple disk drives. Disk striping
can speed up operations that retrieve data from disk storage. Computers that use disk
striping generally allow the user to select the data unit size or stripe width
.
DMA
— direct memory access — A channel that allows certain types of data transfer
between RAM and a device to bypass the processor.
docking device
— See
APR
.
DMTF
— Distributed Management Task Force — A consortium of hardware and
software companies who develop management standards for distributed desktop,
network, enterprise, and Internet environments.
domain
— A group of computers, programs, and devices on a network that are
administered as a unit with common rules and procedures for use by a specific group
of users. A user logs on to the domain to gain access to the resources.
DRAM
— dynamic random-access memory — Memory that stores information in
integrated circuits containing capacitors.
driver
— Software that allows the operating system to control a device such as a
printer. Many devices do not work properly if the correct driver is not installed in the
computer.
DSL
— Digital Subscriber Line — A technology that provides a constant, high-speed
Internet connection through an analog telephone line.
dual-core
— An Intel
®
technology in which two physical computational units exist
inside a single processor package, thereby increasing computing efficiency and multi-
tasking ability.
