Configuration Files
These are files containing data which define the configuration after booting.
Examples of such files are CONFIG.SYS, AUTOEXEC.BAT and the registry.
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).
Collective term for mouse pointer and text cursor.
Keypad on the keyboard for controlling the cursor.
D
DC
Direct Current. Unidirectional electrical current.
DIMM
Dual Inline Memory Module. Memory RAM chips that are installed on the PCB,
similar to the more common SIMM (Single Inline Memory Module) chips. The
DIMM with its 64-bit data bus architecture has connections on both sides which are
connected to different circuits for processing different instructions. SIMMs,
however, have a 32-bit data bus architecture where all lines are connected to the
same circuit for processing the same instructions. DIMMs can be installed in the
computer as single chip, SIMMs, on the contrary, only in pairs.
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.
Cursor
