Input, output, PROCESS, and Storage
Disk drive storage can be both an input and an output device.
A touch screen is both input and output. The touch sensor is input, the display screen is output.
Output. Even if the screen is a touchscreen, the screen itself is still output. The input is handled through a conductive layer on top of the screen, ultrasonic waves in front of the screen, or from an electrostatic field in front of the screen and not from the screen itself.
Output. An actuator is a little motor that moves when it receives an input.
