device. A mechanical, electrical, or electronic piece of equipment designed to serve a special purpose or perform a special function. device driver. A file that contains the code needed to use an attached device. DMA. Direct memory access. duplex. Pertaining to communication in which data can be sent and received at the same time. Synonymous with full-duplex (FDX).. Contrast with half-duplex (HDX). diagnostic. Pertaining to the detection and isolation of errors in programs and faults in equipment. digital. (1) Pertaining to data in the form of digits. (A) (2) Contrast with analog. E ECC. Error correcting code. EEPROM. Electrically erasable programmable read-only memory. DIMM. Dual inline memory module. EISA. Extended industry standard architecture. direct access storage device (DASD). A nonvolatile-storage device, such as a diskette drive, hard disk drive, or CD-ROM drive, in which access time is effectively independent of the location of the data on the storage medium. electrically erasable programmable read-only memory (EEPROM). EPROM that can be reprogrammed while it is in the computer. EPROM. Erasable programmable read-only memory. direct memory access (DMA). The transfer of data between memory and input/output devices without microprocessor intervention. erasable programmable read-only memory (EPROM). A PROM that can be erased by a special process and reused. (T) diskette. A small magnetic disk enclosed in a jacket. (T) diskette drive. The mechanism used to seek, read, and write data on diskettes. It can be installed in, or attached to, a computer. display. A component capable of displaying information on a viewing surface; for example, a cathode ray tube or a gas panel. extended industry standard architecture (EISA). An expansion bus architecture used in a network server that provides compatibility among hardware components. Ethernet. A 10-Mbps baseband local area network that allows multiple stations to access the transmission medium at will without prior coordination, avoids Glossary 299
