for desktop, enterprise, and Internet environments.
Working with key technology vendors and affiliated
standards groups, the DMTF is enabling a more
integrated and efficient approach to management.
DRAM
Dynamic random-access memory (
). Referred to
as "dynamic" because it must be regularly refreshed,
unlike
, which retains a value as long as power
is supplied. See also
and
.
DRDRAM
dynamic random-access memory
(
). Provides a 16-bit
, rather than the 8-
bit
bus. At a speed of 800
, the peak data
transfer rate is 1.6 billion
. DRDRAM uses
to accelerate processing, allowing up to
eight operations to be performed simultaneously.
DTE
Data terminal equipment. In computer data
transmission, DTE is the
interface that a
computer uses to exchange data with a modem or
other
serial
device. See also
DVD
Digital versatile disc. An optical form of storage
media, typically used for movies. DVD has improved
capacity and bandwidth compared with the
Most DVD drives support CD media as well.
ECC
Error checking and correction. A type of
that
checks data that is being read or transmitted for errors
and, when necessary, corrects the errors. See also
ECP
Extended Capabilities Port. A
design that
provides improved bidirectional data transmission.
Like
, it uses
to transfer data and often
improves performance.
such as printers that
connect to the computer’s parallel port are designed
to take advantage of the ECP standard.
EDO
Extended-data out. A type of
that improves the
time to read from memory on faster
such as the Intel Pentium. For faster computers,
different types of
are considered. See also
.
EIDE
Enhanced integrated device electronics. An improved
drives. EIDE uses Logical Block Addressing, which
allows for hard-drive storage capacities greater than
528
. It makes use of
channels and can
address up to four drives. Also called fast
EMI
Electromagnetic interference. Electrical interference
caused by electromagnetic radiation.
Energy Star
A series of
requirements to decrease the overall
consumption of electricity.
EPA
Environmental Protection Agency.
EPP
design that
provides improved bidirectional data transmission.
Like
, it uses
to transfer data and often
improves performance. Many
that connect to
the computer’s parallel port are designed to take
advantage of the EPP standard.
EPP/ECP
Enhanced Parallel Port (
)/Extended Capabilities
Port (
). A
design that provides
improved bidirectional data transmission, using
. EPP is for nonprinter
. ECP is for
printers and scanners.
EPROM
Erasable programmable read-only memory (
). A
that can be erased and then reprogrammed.
