DRAC II
Acronym for Dell™ OpenManage Remote Assistant
Card, version 2.
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.
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
EMM
Abbreviation for expanded memory manager. A utility
that uses extended memory to emulate expanded
memory on systems with an Intel386™ or higher
microprocessor.
EMS
Abbreviation for Expanded Memory Specification.

EPROM
Acronym for erasable programmable read-only
memory.
ERA
Abbreviation for embedded remote access.
ERA/MC
Abbreviation for embedded remote access modular
computer. See modular system.
ERA/O
Abbreviation for embedded remote access option.
ESM
Abbreviation for embedded systems management,
which is a set of instruction coding in system software
and firmware that notifies a user about potential
hardware problems on a system.
expanded memory
A technique for accessing RAM above 1 MB. To enable
expanded memory on your system, you must use an
EMM. You should configure your system to support
expanded memory only if you run application programs
that can use (or require) expanded memory.
extended memory
RAM above 1 MB. Most software that can use it, such
as the Windows operating system, requires that
extended memory be under the control of an XMM.
external cache memory
A RAM cache using SRAM chips. Because SRAM chips
operate at several times the speed of DRAM chips, the
microprocessor can retrieve data and instructions faster
from external cache memory than from RAM.
FAT
Acronym for file allocation table. FAT and FAT32 are
file systems that are defined as follows:
•
FAT — A file system used by MS-DOS,
Windows 3.x, Windows 95, and Windows 98.

Windows NT
and Windows 2000 also can use the
