tended memory to emulate expanded
memory on computers with an Intel386
™
or higher microprocessor. See also

H[SDQGHG±PHPRU\
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

,
EMM
,
extended
memory
, and
memory manager
.
H[SDQVLRQ±EXV
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.
H[SDQVLRQ¶FDUG±FRQQHFWRU
A connector on the computer±s system
board for plugging in an expansion card.
H[WHQGHG±PHPRU\
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
.
H[WHUQDO±FDFKH±PHPRU\
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.

IODVK±PHPRU\
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.
IRUPDW
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-
