The Restore DVD is used to restore the system partition or the entire hard disk to factory
state if the system has crashed. The bootable DVD contains all the necessary image files.
You can also create a boot disk allowing restoration via the network.
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.
The 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.
Serial ATA Interface for hard disk drives and optical drives with serial data transmission rates
of up to 300 Mbps.
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.
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.
Programming software for the creation of user programs for SIMATIC S7 controllers.
