Are remote controls considered input or output devices?

Remote controls are classified as input devices because their primary function is to send commands to another device, such as a television or media player. When a user presses a button on a remote control, it generates a signal that is transmitted to the device, effectively allowing the user to input instructions like changing the channel, adjusting the volume, or powering the device on or off. This action demonstrates how remote controls serve the purpose of allowing users to interact with other electronic devices by providing input.

While some devices do provide feedback to the user (like lights on a remote indicating that a command has been received), the remote itself does not output information to the user but instead serves to initiate commands. Therefore, it solidifies its role as an input device rather than being characterized as an output device or fitting into another category.
