It can operate through various formats, including AM (Amplitude Modulation) and FM (Frequency Modulation), and is commonly used for broadcasting music, news, talk shows, and other types of programming. The term also encompasses the devices designed to receive these broadcasts, known as radios, which can be standalone units, integrated into other devices, or part of a car’s audio system. Additionally, radio can refer to online broadcasting services or procedures that allow for the distribution of audio content through the internet.
