Why is a touchscreen considered both an input and output device?

Answer and explanation

Correct answer: It displays content and also accepts touch commands

The governing concept is dual-function input and output. A touchscreen displays text, images, buttons, and other information, so it performs an output function. At the same time, its touch-sensitive layer detects a finger or stylus and sends that command to the computer, so it also performs an input function. Therefore option B is correct; it is not mainly a storage, sound-only, or electricity-generating device.
