DEVELOPMENTS

What we have looked at is the very basic telephone system. Today the concept of telephoning has undergone a sea change . The extensive use and application of electronics has led to the replacement of mechanical dialler by a push button dialler , which also allows faster dialling by the advent of the 'tone dialling' format. Further , the area of telephone has been transformed to the world of telecommunication. Cordless phones and celluler phones , together with the internet which connects over telephone lines through the modem( which can transmit data as well)has today changed the way our world ticks.And riding on the crest of such a wave of information technology , we are ready to usher in the new millenium.
