Radio: A radio is a technology that enables the transmission and reception of electromagnetic waves through the air, typically used for communication and broadcasting purposes. It allows for the wireless transmission of sound, primarily music, news, and other audio content to be received by radio devices or receivers. Radios operate within specific frequency ranges, such as AM (Amplitude Modulation) and FM (Frequency Modulation), each offering different sound quality and range characteristics. The technology utilizes antennas to both send and receive signals, facilitating live broadcasts as well as scheduled programming, reaching a wide audience. Radio has played a significant role in media and communication, adapting over time to include digital formats and internet streaming.
