Glossary
DIP switch
A series of tiny switches built into circuit boards that enables you to configure a
circuit board for a particular type of computer or application. DIP switches are
always toggle switches. This means that they have two possible positions: on or
off (or 1 or 0).
direct memory access
DMA speeds up system performance by moving blocks of memory around
inside the computer (typically between I/O devices and memory). This process
enables the microprocessor to spend its time performing other functions.
DLL
See dynamic link library.
DLT
See digital linear tape.
DMA
See direct memory access.
DN
See directory number.
driver
A program that controls a device. Every device, whether it is a printer, disk
drive, or keyboard, must have a driver program. A driver acts like a translator
between the device and programs that use the device.
DSP
See digital signal processor.
dual in-line memory module
The protective packaging for microprocessor chips that provides a safe and
convenient means of installing and removing the chip.
dynamic host configuration protocol
A protocol for dynamically assigning IP addresses to devices on a network.
