Glossary
Cold restart
A start sequence, starting when the computer is switched on. During a cold restart, the
system usually performs some basic hardware checks 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.
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 .
Controller
Integrated hardware and software controllers that control the functions of certain internal or
I/O devices (for example, the keyboard controller).
Disc-At-Once
With this burning technique, data are written to a CD in a single session, and the CD is then
closed. Further write access is then no longer possible.
DP
Display Port: New digital monitor interface.
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.
ECC
Error checking and correction is a method for detecting and correcting errors when saving
and transferring data, frequently used in conjunction with RAM modules with and without
ECC.
EMC directive
EU directive for electromagnetic compatibility. Compliance is confirmed by the CE symbol
and the EC certificate of conformity.
