Description:

The main methods of communication are speaking and listening. One of the limitations of communication through speech is that the listener must be within shouting distance. Through the miracle of science, we can speak to a friend that is far away by sending our voice through the air, wire, or glass fiber in the form of electromagnetic radiation or electronic signals. We can even speak to machines and tell them what to do.
