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 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. .
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.
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.
Drop-down menu
In programs supported by GUI, a menu bar is found on the top margin of the screen. The
menu titles contained in this line can be set either as drop-down or pull-down menus. Drop-
down menus “roll” down as soon as the mouse pointer passes over a menu title. Pull-down
menus only “roll” down when the menu title is clicked on. Functions can then be selected
from the menus by moving the mouse cursor or by clicking a menu item.

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.
Energy options
The energy options can be used to reduce energy consumption of the computer, while
keeping it ready for immediate use. This can be configured in Windows by selecting Settings
> Control Panel > Energy options.
