dual in-line package (DIP): A standard for packaging integrated circuits by enclosing
them in a rectangle of ceramic or plastic with downward-pointing connection
pins.
DSP: A digital signal processor is a chip designed for real-time applications. DSP
techniques are used in PC processors as well as media engines. For example,
some high-end notebooks use a DSP chip to provide Sound Blaster emulation
as well as 28.8 modem support.
duplex: The method used to transmit data in both directions between two devices.
Synonymous with full duplex. See also half duplex, full duplex.
E
EISA: Extended ISA, an expansion bus design which maintains compatibility with ISA but
provides a 32-bit data path and additional features. It provides much faster
data throughput than ISA and is used in high performance servers.
emulation: A technique in which a device or program imitates another device or program.
enable: To turn on a computer option.
erase: See delete.
error-correcting code: Code designed for transmission of electronic data, that encodes
data in such a way that transmission errors may be detected and corrected by
examination of the encoded data on the receiving end. Error-correcting code is
used in most modem and in some RAM. In the latter case, circuitry is used that
generates checksums to correct errors greater than one bit.
escape: 1) To cancel the task currently in progress. 2) A code (ASCII code 27, generated
by the ESC key) telling the computer that what follows are commands, not
data. Used with peripheral devices such as printers and modems.
