  • main graphic processor
  • generates electron in CRT
  • a kind of display that requires a higher refresh rate
  • the fly-back of electron beams from one scanline to next line
  • when hit by electron beam it generates the light
  • is a fricker free display
  • a discpline of producing picture or images using a computer
  • it is a vector graphics display
  • frees the CPU from the graphics chores
  • avoids the emitted electron to spread out
  • this technique is not available in vector displays
  • determine the quality of the pictures on printers
  • the maximum number of points that can be displayed without overlap on the CRT
  • initial coordinates of graphic object
