Everything about Radio
Use of radio waves for communication
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. Wikipedia →

📖 Definitions
Noun The technology that allows for the transmission of sound or other signals by modulation of electromagnetic waves.
Noun A device that can capture (receive) the signal sent over radio waves and render the modulated signal as sound.
Noun Any audio playing device, such as the on-board entertainment system in a car, usually including a radio receiver as well as the capability to play audio from recorded media; see also car radio.
Noun A device that can transmit radio signals.
