Glossary
PEG interface
PCI Express for Graphics. Graphics interface with 16 PCIe lanes for expansions with
graphics modules.
Pixel
PixElement. The pixel represents the smallest element that can be reproduced on-screen or
on a printer.
Plug&Play
Generally, a reference to the ability of a computer to automatically configure the system for
communication with peripheral devices (for example monitors, modems or printers). The
user can plug in a peripheral and "play" it at once without manually configuring the system. A
Plug&Play PC requires both a BIOS that supports Plug&Play and a Plug&Play expansion
card.
PXE server
A Preboot Execution Environment server is part of a network environment and can provide
software to connected computers even before they boot. This can involve operating system
installations or servicing tools, for example.
RAID
Redundant Array of Independent Disks: Data storage system which is used to save data and
the corresponding error correction codes (parity bits, for example) to at least two hard disk
volumes in order to enhance reliability and performance. The hard disk array is controlled by
management programs and a hard disk controller for error correction. The RAID system is
usually implemented in network servers.
Recovery
Contains the tools for configuring hard disks and the Windows operating system.
Redundancy
Function blocks are available several times identically and thus increase the reliability and
operational safety. Example redundant power supply: Only one power supply is required in
normal operation. Two power supplies are available in redundant operation: The second
power supply ensures the power supply of the device in the event of a failure of the first.
Reset
Hardware reset: Reset/restart of the PC using a button/switch.
