Glossary

several different forms of memory, such as integrated memory (ROM and RAM) and
add-in memory modules (DIMMs).
memory key
— A portable flash memory storage device integrated with a USB
connector.
MHz
— Megahertz.
mirroring
— A type of data redundancy in which a set of physical drives or memory
modules stores data and one or more sets of additional drives or memory modules
stores duplicate copies of the data. Mirroring functionality is provided by software. See
also
striping
and
RAID
.
mm
— Millimeter(s).
ms
— Millisecond(s).
NAS
— Network Attached Storage. NAS is one of the concepts used for implementing
shared storage on a network. NAS systems have their own operating systems,
integrated hardware, and software that are optimized to serve specific storage needs.
NIC
— Network interface controller. A device that is installed or integrated in a
system to allow connection to a network.
NMI
— Nonmaskable interrupt. A device sends an NMI to signal the processor about
hardware errors.
ns
— Nanosecond(s).
NVRAM
— Nonvolatile random-access memory. Memory that does not lose its
contents when you turn off your system. NVRAM is used for maintaining the date,
time, and system configuration information.
parity
— Redundant information that is associated with a block of data.
parity stripe
— In RAID arrays, striped hard drives containing parity data.
partition
— You can divide a hard drive into multiple physical sections called
partitions
with the
fdisk
command. Each partition can contain multiple logical drives.
You must format each logical drive with the
format
command.
PCIe
— Peripheral Component Interconnect Express. A standard for local-bus
implementation.
PDU
— Power distribution unit. A power source with multiple power outlets that
provides electrical power to servers and storage systems in a rack.
peripheral
— An internal or external device, such as a diskette drive or keyboard,
connected to a system.
pixel
— A single point on a video display. Pixels are arranged in rows and columns to
create an image. A video resolution, such as 640 x 480, is expressed as the number of
pixels across by the number of pixels up and down.
