    • This section describes the difference between circuit switching (CS) and packet switching (PS).

      PS is used for time insensitive applications such as internet/email/SMS/MMS/VOIP etc. In CS even if user is not talking the channel cannot be used by any other users, this will waste the resource capacity at those intervals.

       
      The example of circuit switched network is PSTN and example of packet switched network is GPRS/EDGE. Following table summarizes difference between circuit switching and packet switching of type datagram and virtual circuit.
