With some memory modules, the configuration of the memory
banks is dependent on the motherboard’s chip set. Information on
this can be found in the motherboard documentation.
Detailed information about slots and the BIOS can be found in the
documentation for the motherboard.
2.5 The graphics card
The graphics card is a hardware component of the computer,
which allows information to be processed and displayed on a
monitor.
As digital data is used inside the PC, while traditional tube monitors
only work with analog signals, the fundamental task of the graphics
card is to convert the digital information from the PC into analog
signals for the monitor.
Recently, flat-screen monitors with DVI digital input (Digital Visual
Interface) have come into use. These devices process the digital
image signal directly in the monitor.
The essential components of a graphics card are the graphics
processor, the memory, the RAMDAC (Random Access Memory
Digital Analog Converter), the internal bus and the interfaces to the
motherboard, monitor and possibly a TV.
The graphics card is inserted in a specially designed AGP
(Accelerated Graphics Port) or PCI Express X16 slot on the
motherboard. The graphics card may also be integrated on the
motherboard ("graphic on board").

For low-fatigue work on the PC, it is important from an ergonomic
point of view that the refresh rate is set correctly. Even at high
resolutions, this should not be below 85 Hz.
