The transmitter sends feedback to a receiver. The medium is the channel message between the transmitter and the receiver.

The ancient Greeks used the method of Techne.  WIFI is only 2o years old, but Techne is as old as humanity. It's the basic model of communication. Technology doesn't refer to what is on your desk but home you use it.
The channel which we communicate heavily influences what we receive.
At school were all bombarded with NOISE.
