Vector Display: 
* Only lines can be drawn 
* Locations are converted to analog voltage applied to the deflection yoke 
* Lines drawn by gradual change of voltage 
* Also known as random scan 
* Refresh time is scene dependent 
* Old fashioned - very uncommon today 

Raster Display: 
* Discrete grid of elements (frame buffer’s pixels) 
* Complex to draw “nice” lines 
* Arbitrary shapes can be drawn 
* Frame buffer is scanned, one line at a time 
* Used almost everywhere
