Questions and Answers
  • 1. 
    The difference between a raster and a vector device is that
    • A. 

      A raster device is more expensive than a vector device and a raster device produces complete lines.

    • B. 

      A raster device is an input device while a vector device is an output device

    • C. 

      A raster device treats the output as a whole whilst a vector device treats the global output as being made up out of a number of different parts. So vector devices produce complete lines whilst raster devices produce images as a series of dots.

    • D. 

      Raster devices are output devices while vector devices are input devices.
