Editing Framebuffer (section)

== RAM on the video card ==
{{see also|Video memory}}
Video cards always have a certain amount of RAM. A small portion of this RAM is where the bitmap of image data is "buffered" for display. The term ''frame buffer'' is thus often used interchangeably when referring to this RAM.

The CPU sends image updates to the video card. The video processor on the card forms a picture of the screen image and stores it in the frame buffer as a large bitmap in RAM. The bitmap in RAM is used by the card to continually refresh the screen image.<ref>{{cite web|url=http://karbosguide.com/hardware/module7b1.htm|title=An illustrated Guide to the Video Cards|work=karbosguide.com}}</ref>
