Q. What do you mean by Video Memory ?

The quality of a video display relies a lot on how quickly can the framebuffer be accessed and be updated by video system. In early video systems video memory was just a fixed area of system RAM.

Video RAM is again part of system RAM. UMA is what you get in modern low-cost motherboards with on-board video and sound cards etc.
