It is both. The output device shows you images on the screen, while the input device allows you to interact with objects on the screen (e.g., touch the screen to select an option).

What is the difference between output and input?If you sing into a microphone you can hear the microphone's output.Sound coming out of the power amp to the speakers.That is the input of the loudspeaker.Do you see the difference?Your voice is the microphone's input. Its output is electrical impulses that are input to the amplifier. The amplified impulses are the output of the amplifier and input to the speaker. Sound waves are output of the speaker and input to your ears.
Output is always greater than input. The output is multiplied from input.
The formula for work exerted by each simple machine is: Lever: Work = Input force × Input distance = Output force × Output distance Inclined plane: Work = Input force × Input distance = Output force × Output distance Pulley: Work = Input force × Input distance = Output force × Output distance Wheel and axle: Work = Input force × Input radius = Output force × Output radius Wedge: Work = Input force × Input distance = Output force × Output distance Screw: Work = Input force × Input distance = Output force × Output distance
I expect you mean "Is Card reader/writer input or output?". If this is so, it is both an input and output device. Whenever you are trying to categorize a device as Input or Output, think of how it looks from the computer.If the computer is transmitting data to it, it is an Output device.If the computer is receiving data from it, it is an Input device.
