Glossary
300
dpi: Dots per inch. The number of ink dots printed per linear inch. For
example, a printer specification of 300 x 300 dpi means that the
printer can make 300 dots per inch both vertically and horizontally.
drag: To hold down the AccuPoint II control button or mouse button
while moving the cursor. In Windows, this refers to the primary
AccuPoint II control button or left mouse button, unless otherwise
stated.
driver: See device driver .
Dual SuperTwist Nematic: A type of LCD display.
duplex: The method used to transmit data in both directions between two
devices. Synonymous with full duplex. See also half duplex, full
duplex.
DVD-ROM: A very high-capacity storage medium that uses laser optics
for reading data. The computer can read data from these discs, but
cannot write data to the discs. Each disc can hold as much data as
several CD-ROMs.
Digital Simultaneous Voice and Data (DSVD) : An all-digital technology
for concurrent voice and data (SVD) transmission over a single
analog telephone line.
E
EDO DRAM (Extended Data Output Dynamic Random Access
Memory): A new DRAM technology that increases the memory
performance of your computer. It provides the following advantages
over previous types of DRAM: 1) shorter Page Mode cycle times, 2)
increased peak bandwidth, and 3) simplified constraints on access
timing.
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 modems and in
some RAM. In the latter case, circuitry is used that generates
checksums to correct errors greater than one bit.
