Product Key
Also referred to as
Product ID
. See
COA
.
PS/2
Personal System/2
. A
mini-DIN
connector on your computer that is typically
used to connect keyboard or mouse cable connectors.
PXE
Pre-boot eXecution Environment
. A standard of
WfM
that allows networked
computers that do not have an
OS
to be configured and started remotely.
PXE benefits include:
•
The client computer does not necessarily need its own OS or even a hard drive.
•
The client computer can be remotely shut down and restarted.
•
Since PXE is an industry standard, new computers can easily be added to the
network.
R
RAID
Redundant Array of Independent
Disks
. A system of two or more drives working
together for performance and fault tolerance. RAID drives are typically used
on servers and high-end
PCs
.
There are a number of different RAID levels. The three most common are 0,
3, and 5:
•
Level 0:
Provides
data striping
but no redundancy. This improves performance
but does not provide fault tolerance.
•
Level 3:
Same as Level 0, but also reserves one dedicated drive for error
correction data, providing good performance and some level of fault tolerance.
•
Level 5:
Provides data striping at the
byte
level and also stripe error correction
information. This results in excellent performance and good fault tolerance.
RAM
Random-access memory
. The primary temporary storage area for program
instructions and data. RAM is stored in
chips
on small circuit boards called
SIMMs
,
DIMMs
, or
RIMMs
, that attach to the system board. RAM, unlike
ROM
, is volatile, which means that, when you turn off your computer, any
information stored in RAM is lost.
Rambus
Rambus is a memory technology that is designed to work with existing system
board standards as an alternative to
DRAM
. See also
RIMM
,
RDRAM
, and
DRDRAM
.
