What is a "radio"?
A radio is a piece of equipment designed to receive and play audio broadcasts transmitted over radio waves. It typically includes a tuner to select different radio stations, speakers to output sound, and controls for adjusting volume and frequency. Radios can be portable or stationary and may include features such as digital displays, alarms, and the ability to play music from external sources like CDs or digital devices. They allow listeners to access a variety of programs, including music, news, and talk shows.
