EMM

expanded memory manager. A utility that uses extended memory to emulate expanded memory on computers with an Intel386™ or higher 
microprocessor.

EMS

Expanded Memory Specification

EPROM

erasable programmable read-only memory

ESD

electrostatic discharge

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.

FAT

file allocation table. The file system structure used by MS-DOS to organize and keep track of file storage. The Microsoft Windows NT and OS/2
operating systems can optionally use a FAT file system structure.

flash memory

A type of EEPROM chip that can be reprogrammed 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 deletes all data stored on the disk.
