Answer 2

It seems like you're referring to a remote control. A remote control is a device used to wirelessly operate electronic devices such as televisions, audio systems, and more. It typically has buttons or controls that allow users to adjust settings, change channels, control volume, and perform other functions without needing to be directly in front of the device they are controlling. Remote controls communicate with the target device using infrared signals or other wireless technologies.
