Rádio

“Rádio” is the Portuguese word for “radio,” which refers to a technology and medium used for transmitting and receiving sound via electromagnetic waves. It operates by converting audio signals into radio waves, which can then be broadcast over a designated frequency for listeners to receive through radio receivers. Radio can include various formats such as music, news, talk shows, and advertisements, and it may be transmitted over different platforms, including AM (Amplitude Modulation), FM (Frequency Modulation), or digital formats. Radio serves as a vital source of information and entertainment and can also include communication applications such as two-way radio systems.
