The _________ simply reads each successive byte of data from the frame buffer?

   A.) Display Controller
   B.) Digital Controller
   C.) Data Controller
   D.) All of above

Answer: Option 'A'

A Video Display Controller or VDC is an integrated circuit which is the main component in a video signal generator, a device responsible for the production of a TV video signal in a computing or game system. Some VDCs also generate an Audio signal, but in that case it's not their main function.

All the hidden surface algorithms employee image space approach except?

   A.) Depth sort method
   B.) Scan line method
   C.) Back face removal
   D.) Depth buffer method

Answer: Option 'C'

A simple object space algorithm is Back-Face removal (or back face cull) where no faces on the back of the object are displayed. It can only be used on solid objects modeled as a polygon mesh.
