LPT — line print terminal — The designation for a
parallel connection to a printer or other parallel device.
M
Mb — megabit — A measurement of memory chip
capacity that equals 1024 Kb.
Mbps — megabits per second — One million bits per
second. This measurement is typically used for
transmission speeds for networks and modems.
MB — megabyte — A measurement of data storage that
equals 1,048,576 bytes. 1 MB equals 1024 KB. When used
to refer to hard drive storage, the term is often rounded to
1,000,000 bytes.
MB/sec — megabytes per second — One million bytes
per second. This measurement is typically used for data
transfer ratings.
memory — A temporary data storage area inside your
computer. Because the data in memory is not permanent,
it is recommended that you frequently save your files
while you are working on them, and always save your files
before you shut down the computer. Your 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.
memory address — A specific location where data is
temporarily stored in RAM.
memory mapping — The process by which the computer
assigns memory addresses to physical locations at start-up.
Devices and software can then identify information that
the processor can access.
memory module — A small circuit board containing
memory chips, which connects to the system board.
MHz — megahertz — A measure of frequency that equals
1 million cycles per second. The speeds for computer
processors, buses, and interfaces are often measured in
MHz.
Mini PCI — A standard for integrated peripherals with
an emphasis on communications such as such as modems
and NICs. Mini PCI is a small card that is functionally
equivalent to a standard PCI expansion card.
modem — A device that allows your computer to
communicate with other computers over analog
telephone lines. Three types of modems include: external,
PC Card or ExpressCard, and internal. You typically use
your modem to connect to the Internet and exchange
e-mail.
media bay — A bay that supports devices such as optical
drives, a second battery, or a Dell TravelLite™ module.
monitor — The high-resolution TV-like device that
displays computer output.
mouse — A pointing device that controls the movement
of the cursor on your screen. Typically you roll the mouse
over a hard, flat surface to move the pointer or cursor on
your screen.
ms — millisecond — A measure of time that equals one
thousandth of a second. Access times of storage devices
are often measured in ms.
N
network adapter — A chip that provides network
capabilities. A computer may include a network adapter
on its system board, or it may contain an PC Card with an
adapter on it. A network adapter is also referred to as a
NIC (network interface controller).
NIC — See network adapter.
notification area — The section of the Windows taskbar
that contains icons for providing quick access to programs
and computer functions, such as the clock, volume
control, and print status. Also referred to as system tray.
ns — nanosecond — A measure of time that equals one
billionth of a second.
NVRAM — nonvolatile random access memory — A type
of memory that stores data when the computer is turned
off or loses its external power source. NVRAM is used for
maintaining computer configuration information such as
date, time, and other system setup options that you can
set.
