A mapping. It need not be a function.
function rule
The value that results from the substitution of a given input into an expression or function is the output. The value substituted into an expression or function is an input.
cost or input
The Boolean expression for an OR gate is represented as ( A + B ), where ( A ) and ( B ) are the input variables. In this expression, the output is true (1) if at least one of the inputs ( A ) or ( B ) is true. If both inputs are false (0), the output will also be false.
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.

is an omr and input or output device?
both input r output
Using the output of first function as the input of the second function.
Input device.
it is an output device
output/input
output and input
a model of interactions between different sectors in an economy
Neither, it is not classified under input or output. It has its own identity
