Input is electricity and output is sound, heat and light.
Depends on what you're referring to. Input could be a switch for example, output would be a fan or light coming on. Eating is an input, you can guess what your output is?
A light bulb is an output device because it produces light when electricity is applied to it. It takes the input of electrical energy and converts it into light energy.
Input to light bulb is Electricity and output is light.
Light Pen is an input Device.
A light bulb can be considered an output device as it converts electrical energy into light energy. In the context of a system, the light bulb would typically be connected to an input device such as a switch or sensor that controls when the light bulb turns on or off. Therefore, while the light bulb itself is an output, its operation is often dependent on input signals.
The input of a light bulb is electricity, which powers the bulb, causing it to emit light as the output.
Light Pen is an input Device.
Light Pen is an input Device.
A output switch is a light switch just with a different name.
Assuming that a sensor (any type, heat, light, sound etc) is connected to something - eg a computer or a switch etc. it is an 'input' device. The device which created whatever is being 'sensed' is an output device. For example if you put a thermometer next to a light bulb to see how hot it is then the bulb is 'output' and the thermometer is 'input'.
You could call the operating system thwarting process between input and output. It inputs your commands from keyboard, mouse and voice etc. Then outputs sound from speakers and light from the monitor.
