Radio

Radio refers to the technology and medium of transmitting audio content through electromagnetic waves. It allows for the delivery of information, music, news, and entertainment over airwaves to be received by radio receivers, such as radios, smartphones, and other devices. The term encompasses both the physical devices that receive these transmissions and the broadcasting process itself, which can occur over AM (Amplitude Modulation), FM (Frequency Modulation), and digital formats. Radio can serve various purposes, including public communication, emergency broadcasting, and personal entertainment. Additionally, radio technology has evolved to include internet streaming, allowing for global access to radio programming beyond traditional broadcast limitations.
