A normal computer monitor is simply an output device; it takes no input from the user. A touchscreen monitor, on the other hand, is both an input and an output device.
It is an input device. Like other input devices, it takes information so it can be processed/stored. An output device, on the other hand, takes care of the displaying or presenting of already processed/stored information.
The processor puts information into an acceptable form for your computer. The input output channel is a physical link that connects the computer to an output or input device.
A scanner is an output device because it doesn't receive data it only sends out data.

A monitor is first and foremost an Output Device because it displays information already held in the computer. Touchscreen monitors that allow you to input information or to use navigational features such as menus, icons and so on are also Input Devices. Another example of a device that is both an input and output device is a joystick with Force Feedback technology.
it all depends on how hard you lift of push your hand.
The output force is the force applied by your hand to the doorknob, while the input force is the force exerted by the doorknob on the door. To find these forces, you can measure the distance from the point where your hand touches the doorknob to the center of the doorknob for input force, and the distance from the same point to where the force is applied by your hand for output force, and then apply the principle of moments.
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
Perhaps it would be better for you to research what "output device" means. If you need to output something, you need an output device. There is simply no alternative to which you can compare it.
Input energy is typically more useful than output energy because input energy is the initial energy put into a system to produce the desired output. Output energy, on the other hand, is the energy produced by the system after losses and inefficiencies have occurred, so it is usually less than the input energy. By maximizing input energy efficiency, we can achieve a more effective output.
The input force on a can opener is the force exerted by the user's hand to turn the handle. The output force is the force that the can opener applies to the can as it punctures and cuts through the lid.
