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

peripheral devices (for example, the keyboard controller).
