Glossary 187
EMI
Abbreviation for electromagnetic interference.
EMM
Abbreviation for expanded memory manager. A utility 
that uses extended memory to emulate expanded 
memory on computers with an Intel386
™
 or 
higher microprocessor.
EMS
Abbreviation for Expanded Memory Specification.
EPP
Abbreviation for Enhanced Parallel Port which provides 
improved bidirectional data transmission. Many devices 
are designed to take advantage of the EPP standard, 
especially devices, such as network or SCSI adapters that 
connect to the parallel port of a portable computer. 
EPROM
Acronym for erasable programmable read-only memory.
ERA
Acronym for embedded remote access.
ERA/O
Acronym for embedded remote access option.
ESD
Abbreviation for electrostatic discharge.
ESM
Acronym for embedded server management.
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 support 
expanded memory only if you run application programs 
that can use (or require) expanded memory.
expansion bus
Your computer contains an expansion bus that allows 
the microprocessor to communicate with controllers 
for peripheral devices, such as a network card or an 
internal modem.
expansion-card connector
A connector on the computer's system board or riser 
board for plugging in an expansion card.
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.
F
Abbreviation for Fahrenheit.
FAT
Acronym for file allocation table. The file system 
structure used by MS-DOS to organize and keep track 
of file storage. The Windows NT
®
 operating systems 
(and later Windows versions) can optionally use a FAT 
file system structure.
FCC
Abbreviation for Federal Communications 
Commission.
FEPROM
Acronym for Flash Erasable Programmable Read-Only 
Memory. Flash memory is a kind of nonvolatile storage 
device similar to EEPROM, but the erasing is done only 
in blocks or the entire chip.
FiFO
Abbreviation for first-in, first-out. In computer 
programming, FIFO (first-in, first-out) is an approach 
to handling program work requests from queues or 
stacks so that the oldest request is handled next
