what is different between multiplexer and demultiplexer?

Answer Posted / ashok

I agree with Priyadarshi sahu.But here one thing do u
remember.actually in telecommunications,ISP we use both the
mux and demux .

Mux means --we give many inputs and get single input only
Demux-------we give single input and get more outputs.

ex:consider one Internet service provider(ISP) location

Here in POP(Point of Presence)all are using MUX and Demux
because lot of customers are connected and at customer side
also they connected lot of systems and the data flow b/w all
the systems as well as pop
