Glossary 9
/,0
Acronym for Lotus/Intel/Microsoft. LIM
usually refers to version 4.0 of the EMS.
/1
Abbreviation for load number.
ORFDOEXV
On a computer with local-bus expansion
capability, certain peripheral devices
(such as the video adapter circuitry) can
be designed to run much faster than they
would with a traditional expansion bus.
Some local-bus designs allow peripherals
to run at the same speed and with the
same width data path as the computer’s
microprocessor.
/37 Q
The MS-DOS device names for the first
through third parallel printer ports on your
computer are LPT1, LPT2, and LPT3.
/81
Acronym for logical unit number.
/9'
Acronym for low voltage differential.
P
Abbreviation for meter(s).
P$
Abbreviation for milliampere(s).
P$K
Abbreviation for milliampere-hour(s).
PDWKFRSURFHVVRU
See coprocessor .
0%
Abbreviation for megabyte(s). The term
megabyte means 1,048,576 bytes; how-
ever, when referring to hard-disk drive
storage, the term is often rounded to mean
1,000,000 bytes.
0%5
Abbreviation for master boot record.
0'$
Abbreviation for monochrome display
adapter.
PHPRU\
A computer can contain several different
forms of memory, such as RAM, ROM,
and video memory. Frequently, the word
memory is used as a synonym for RAM; for
example, an unqualified statement such as
“
…
a computer with 8 MB of memory” re-
fers to a computer with 8 MB of RAM.
PHPRU\DGGUHVV
A specific location, usually expressed as
a hexadecimal number, in the computer’s
RAM.
PHPRU\PDQDJHU
A utility that controls the implementation
of memory in addition to conventional
memory, such as extended or expanded
memory. See also
conventional memory ,
EMM , expanded memory , extended
memory , HMA , upper memory area , and
XMM .
0*$
Abbreviation for monochrome graphics
adapter.
0+]
Abbreviation for megahertz.
PLFURSURFHVVRU
Because it is the primary computational
chip inside the computer, it is customary
to refer to the microprocessor as “the
computer’s brain.” The microprocessor
contains an arithmetic processing unit and
a control unit. Software written for one
microprocessor must usually be revised
to run on another microprocessor. CPU is
a synonym for microprocessor.
PLQ
Abbreviation for minute(s).
PLUURULQJ
A type of data redundancy that uses a set
of physical drives to store data and one or
more sets of additional drives to store du-
plicate copies of the data. Mirroring is the
preferred data redundancy technique in
lower-capacity systems and in systems
where performance is extremely impor-
tant. See also
guarding , RAID 1 , and
RAID 10 .
