Glossary

APIC mode
Advanced peripheral interrupt controller. 24 interrupt lines are available.
Automation system
A programmable controller (PLC) of the SIMATIC S7 system consist of a central controller,
one or several CPUs, and various I/O modules.
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 be made if a memory expansion, new expansion card or drives are
to be activated.
Cache
High-speed access buffer for interim storage (buffering) of requested data.
Card retainer
The card retainer is used to fasten expansion cards and ensure safe contact and transport.
Large, heavy expansion cards are particularly affected by shocks and vibrations. We
therefore recommend that you use the card retainer for this type of expansion card. Very
short, compact and light expansion cards are also available on the market. The card retainer
was not designed for these expansion cards because standard fastening is sufficient for
them.
CE marking
CE stands for Communauté Européenne. The CE symbol confirms the conformity of the
product with all applicable EC directives such as the EMC Directive.
Chipset
The chipset sits on the motherboard and connects the processor to the RAM, the graphics
card, the PCI bus and the external interfaces.
Configuration files
These are files containing data which define the configuration after restart. Examples of such
files are CONFIG.SYS, AUTOEXEC.BAT and the registry files .
