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.
RAL
Restricted Access Location: Installation of the device in a production facility with restricted
access, for example, a locked control cabinet.
Reset
Hardware reset: Reset/restart of the PC using a button/switch.
Restart
Warm restart of a computer without switching the power off (Ctrl + Alt + Del)
ROM
Read-Only Memory ROM is a read-only memory in which every memory location can be
addressed individually. The programs or data are permanently stored and are not lost in the
event of a power failure.
S.M.A.R.T
Self-Monitoring, Analysis and Reporting Technology (SMART or S.M.A.R.T.) is an industry
standard integrated in storage media. It makes for permanent monitoring of important
parameters and early detection of imminent problems.
SATA
Serial ATA Interface for hard disk drives and optical drives with serial data transmission rates
of up to 300 Mbps.
SETUP (BIOS Setup)
A program in which information about the device configuration (that is the configuration of
the hardware on the PC/PG) is defined. The device configuration of the PC/PG is preset with
defaults. Changes must therefore be entered in the SETUP if a memory expansion, new
modules or a new drive are added to the hardware configuration.
SSD (Solid State Drive)
A Solid State Drive is a drive that can be installed like any other drive; it does not contain a
rotating disk or other moving parts because only semiconductor memory chips of similar
capacity will be used. This design makes SSDs more rugged, provides shorter access times,
low energy consumption and rapid data transfer.
