Radio is a technology that uses electromagnetic waves to transmit sound, music, or data wirelessly. A radio transmitter converts sound into radio waves, and a radio receiver captures those waves and converts them back into sound.

Yes. Many radio stations now stream their content live over the internet, often called internet radio or web radio, accessible via websites or mobile apps.
Analog radio (AM/FM) transmits signals continuously, while digital radio (like DAB – Digital Audio Broadcasting) uses digital signals for clearer audio, more stations, and additional information like song titles and traffic updates.
