Radyo, or radio, is a technology that allows for the transmission of audio content over electromagnetic waves. It operates by converting sound into electrical signals, which are then broadcasted through antennas. Listeners can tune in to different frequencies to access various channels, providing a wide range of programming, including music, news, and talk shows. The invention of radyo dates back to the late 19th century, with key figures like Guglielmo Marconi playing a significant role in its development. Today, radyo remains a popular medium for communication and entertainment, with both traditional AM/FM stations and digital platforms available to audiences worldwide.
