system resources from a corresponding
EISA configuration file.
EMC
Abbreviation for Electromagnetic
Compatibility.
EMI
Abbreviation for electromagnetic
interference.
EMM
Abbreviation for expanded memory
manager. A software utility that uses ex-
tended memory to emulate expanded
memory on computers with an Intel386
or higher microprocessor. See also conven-
tional memory, expanded memory,
extended memory, memory manager,
and XMM.
EMS
Abbreviation for Expanded Memory Spec-
ification. See also expanded memory,
memory manager, and XMS.
EPROM
Acronym for erasable programmable
read-only memory.
ESD
Abbreviation for electrostatic discharge.
Refer to “Safety Instructions” at the front
of your User’s Guide for a complete discus-
sion of ESD.
ESDI
Acronym for enhanced small-device
interface.
expanded memory
A technique for accessing RAM above
1 MB. To enable expanded memory on
your computer, you must use an EMM.
You should configure your system to sup-
port expanded memory only if you run
application programs that can use (or
require) expanded memory. See also
conventional memory, EMM, extended
memory, and memory manager.
expansion bus
Your computer contains an expansion bus
that allows the microprocessor to com-
municate with controllers for peripheral
devices, such as a network card or an in-
ternal modem.
expansion-card connector
A connector on the computer’s system
board for plugging in an expansion card.
extended memory
RAM above 1 MB. Most software that can
use it, such as Windows, requires that ex-
tended memory be under the control of
an XMM. See also conventional memory,
expanded memory, memory manager,
and XMM.
external cache memory
A RAM cache using SRAM chips. Be-
cause SRAM chips operate at several
times the speed of DRAM chips, the
microprocessor can retrieve data and in-
structions faster from external cache
memory than from RAM.
F
Abbreviation for Fahrenheit.
FAT
Acronym for file allocation table. The file
system structure used by MS-DOS to or-
ganize and keep track of file storage. The
Microsoft Windows NT
®
operating sys-
tem can optionally use a FAT file system
structure.
FCC
Abbreviation for Federal Communications
Commission.
flash memory
A type of EEPROM chip that can be re-
programmed from a utility on diskette
while still installed in a computer; most
EEPROM chips can only be rewritten with
special programming equipment.
format
To prepare a hard-disk drive or diskette for
storing files. An unconditional format de-
letes all data stored on the disk. The
format command in MS-DOS 5.0 or higher
includes an option that allows you to unfor-
mat a disk, if you have not yet used the disk
for file storage.
