Radio

Radio is a technology that allows for the transmission and reception of signals through electromagnetic waves, specifically in the radio frequency spectrum. It enables the broadcasting of audio content, such as music, news, and talk shows, to be received by radio receivers, which convert the signals back into sound. The term “radio” can also refer to the medium itself, as well as to devices that receive these signals. Radio broadcasting has evolved from analog to digital formats and can be categorized into various types, including AM (Amplitude Modulation), FM (Frequency Modulation), and digital radio. It serves as an important communication tool and entertainment source, capable of reaching large audiences across vast distances.
