Glossary 293
LPT Port
Line print terminal. The typical designation for a
parallel port connection to a printer or other parallel
device. Most computers support one or two parallel
ports designated as LPT1 and LPT2.
LVD
Low voltage differential. A form of SCSI interface that
will be formalized in the SCSI-3 specification. LVD
uses less power than the present differential drive, is
less expensive, and supports the higher speeds of
Ultra-2 SCSI drives. LVD requires 3.3 VDC instead
of 5 VDC, the previous standard.
m
Meter. A measurement of length that equals 39.37
inches.
mA
milliAmpere. A measurement of current that equals
one thousandth of an A .
Mb
Megabit. A measurement of memory chip capacity
that equals 1024 Kb .
Mbps
Megabits per second. A measurement of network and
modem transmission speeds that equals one million
bits per second.
MB
Megabyte. A measurement of data storage that equals
1,048,576 bytes . 1 MB equals 1024 KB . When
referring to hard drive storage, the term is often
rounded to mean 1 million bytes.
MBA
Managed boot agent. Provides multiple PXEs and
allows a computer to boot from a network server.
MBps
MB (s) per second. A measurement of data
transmission speed.
Memory Address
Addresses assigned to physical memory locations by
the computer at start-up. These addresses allow
devices and software applications to identify
information that the microprocessor can access. This
process is referred to as Memory Mapping .
Memory Mapping
The process by which the computer assigns memory
addresses to physical memory locations at start-up.
Devices and software applications can then identify
information that the microprocessor can access.
MHz
Megahertz. A measurement of frequency that equals
one million Hz .
Microprocessor
A computer chip that interprets and executes
program instructions. Also referred to as the CPU .
See also Bus Speed .
MIF
Management Information Format. A syntax for
describing information for manageable hardware and
software components that can be installed on a
computer. See also COO , WBEM , and WfM .
min
Minute(s). A measurement of time that equals 60 sec .
Mini-DIN
A form of DIN connector that is round, has 6 pins,
and is typically used to connect PS/2 keyboard or
mouse cable connectors.
mm
Millimeter. A measurement of length that equals one
thousandth of a meter or 1/25 inch.
Modem
A shortened reference to modulator/demodulator.
Modems convert analog data into digital data and
