VGA Connector
A type of graphics connector, sometimes also called an analog connector.
It is the most common type of video connector available, consisting 15-pins
set in three rows. The “VGA” is an acronym for “Video Graphics Array,”
which is also the name for the video resolution mode of 640x480 pixels, the
lowest standard resolution supported by virtually all video cards.
Z-buffer
The portion of video memory that keeps track of which onscreen elements
can be viewed and which are hidden behind other objects. In the case of a
3D image, it keeps track of which elements are occluded by the foreground
in relation to the user’s perspective, or by another 3D object.
