Siemens SIMATIC Series Operating Instructions Manual page 187

Programmable controller
The programmable controllers of the SIMATIC S5 system consist of a central controller, one
or more CPUs, and I/O modules, for example.
Recovery DVD
Contains the tools for configuring hard disks and the Windows operating system.
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)
Restore DVD
The Restore DVD is used to restore the system partition or the entire hard disk to factory
state if the system has crashed. The DVD contains all the necessary image files and is
bootable.
S.M.A.R.T
SMART or S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is an industry
standard that is installed 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.
Session-At-Once
In session-at-once, the CD can be written to both with an audio session and a data session.
The two sessions are written to at once (as in disc-at-once).
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.
