COM interface
The COM interface is a serial V.24 interface. The interface is suitable for asynchronous data
transfer.
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).
Device configuration
The configuration of a PC or programming device contains information on hardware and
device options, such as memory configuration, drive types, monitor, network address, etc.
The data are stored in a configuration file and enable the operating system to load the
correct device drivers and configure the correct device parameters. . If changes are made to
the hardware configuration, the user can change entries in the configuration file using the
SETUP program. .
Drivers
Program parts of the operating system. They adapt user program data to the specific formats
required by I/O devices such as hard disk, printers, and monitors.
EMC directive
Directive concerning Electromagnetic Compatibility. Compliance is confirmed by the CE
marking and the EC certificate of conformity.
Energy management
The energy management functions of a modern PC allow individual control over the current
consumption of vital computer components (e.g. of the monitor, hard disk and CPU), by
restricting their activity based on the current system or component load. Energy
management is of particular importance for mobile PCs.
