    Radio is a way to send electromagnetic signals over a long distance, to deliver information from one place to another using technology. When radio signals are sent out to many receivers at the same time, it is called a broadcast.

    Defining radio

    Broadcasting is a one-way transmission of information from a radio transmitter to receivers belonging to a public audience. That's why England has BBC (British Broadcasting Corporation). But it can be a two-way transmission like in mobile phones


    The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Like magic, radio waves are signals that travel through the air in a straight line leading information.Now its history goes along with internet.
