DPMS
Abbreviation for Display Power Management Signaling.
A standard developed by the Video Electronics
Standards Association (VESA
®
) that defines the
hardware signals sent by a video controller to activate
power management states in a monitor. A monitor is
said to be DPMS-compliant when it is designed to
enter a power management state after receiving the
appropriate signal from a system's video controller.
DRAC 4
Acronym for Dell™ Remote Access Controller 4.
DRAC 5
Acronym for Dell Remote Access Controller 5.
DRAC II
Acronym for Dell OpenManage™ Remote Assistant
Card II.
DRAC III
Acronym for Dell Remote Access Card III.
DRAC III/XT
Acronym for Dell Remote Access Card III/XT.
DRAM
Acronym for dynamic random-access memory. A
system's RAM is usually made up entirely of DRAM
chips. Because DRAM chips cannot store an electrical
charge indefinitely, your system continually refreshes
each DRAM chip in the system.
drive-type number
Your system can recognize a number of specific hard
drives. Each is assigned a drive-type number that is
stored in NVRAM. The hard drive(s) specified in your
system's System Setup program must match the actual
drive(s) installed in the system. The System Setup
program also allows you to specify physical parameters
(logical cylinders, logical heads, cylinder number, and
logical sectors per pack) for drives not included in the
table of drive types stored in NVRAM.
DSM SA Connection Service
Acronym for Dell Systems Management Server
Administration. An application that makes Web pages
available for viewing by Web browsers using the
HTTPS protocol. See "Web server".
DTE
Abbreviation for data terminal equipment. Any device,
such as a computer system, that can send data in digital
form by means of a cable or communications line. The
DTE is connected to the cable or communications line
through a data communications equipment (DCE)
device, such as a modem.
ECC
Abbreviation for error checking and correction.
ECP
Abbreviation for Extended Capabilities Port.
EDO
Acronym for extended data output dynamic random
access memory which is a type of DRAM that is faster
than conventional DRAM. EDO RAM can start
fetching the next block of memory at the same time
that it sends the previous block to the microprocessor.
EEPROM
Acronym for electrically erasable programmable read-
only memory.
EIDE
Abbreviation for enhanced integrated drive electronics.
EIDE devices add one or more of the following
enhancements to the traditional IDE standard:
• Data transfer rates of up to 16 MB/sec
• Support for drives other than just hard drives, such
as CD and tape drives
• Support for hard drives with capacities greater than
528 MB
• Support for up to two controllers, each with up to
two devices attached
