128-bit:
This refers either to the internal graphics
engine or to the path from the controller to the
graphics memory. 3D Prophet graphics boards have
a true 128-bit subsystem because they incorporate both a 128-bit internal graphics
engine as well as a 128-bit path from the controller to the graphics memory,
thus providing enhanced 2D and 3D performance.
OpenGL
(Open Graphic Library):
A 3D image calculation standard developed by Silicon Graphics, and supported
by most 3D graphic accelerator boards.
Operating
system:
The program that runs the computer. This is
loaded into memory when you boot up your PC and
acts as an interface between hardware and software.
Overclocking:
This involves altering the
settings of the computer system's hardware and/or graphics board memory to run
at a higher clock frequency than originally set by the manufacturer, in an attempt
to improve system performance. There is a risk, albeit slight, that overclocking
will impair your system.
Overlay:
Encrustation of the video signal
(e.g. a DVD film) onto the VGA image (e.g. the Windows desktop).
