Glossary
CE marking
Communauté Européene The CE mark confirms compliance of the product with
corresponding EC Directives, for example, with the EMC Directive.
Chipset
Located on the motherboard, connects the processor with the RAM, the graphics controller,
the PCI bus, and the external interfaces.
Cold restart
A start sequence, starting when the computer is switched on. The system usually performs
some basic hardware checks within the cold start sequence, and then loads the operating
system from the hard disk to work memory -> boot
COM interface
The COM interface is a serial V.24 interface. The interface is suitable for asynchronous data
transfer.
Compact Flash cards (CF)
Compact Flash is a digital storage medium in card format and without moving parts. The CF
card contains the non-volatile memory and the controller. The interface of the CF card
corresponds with the IDE interface. CF cards can be operated without additional electronics
on PCMCIA or IDE hard disk controllers using a plug and socket adapter. There are two
design forms: CF-I (42.6 x 36.4 x 3.3 mm) and CF-II (42.8 x 36.4 x 5 mm).
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 .
Configuration software
The configuration software updates the device configuration when new modules are installed
. This is done either by copying the configuration files supplied with the module or by manual
configuration using the configuration utility.
Controller
Integrated hardware and software controllers that control the functions of certain internal or
I/O devices (for example, the keyboard controller).
