  1.  Digital circuit are less affected by noise.
  2.  Digital signal maintain there quality over long distances.
  3.  Digital signal carry more information per second than analog signals.
  4.  Digital signal system are generally easy to design.
  5.  Reprogramming is possible.
  6.  Size and Cost is less .
  7.  Power dissipation is less.
  8.  Memories are stable.
  9.  Information Storage is easy.

Disadvantage :  Real world is mainly analog, human does not understand digital data.
