Color channels vs. color IO channels

    What is the difference between changing the value of a color channel
    and changing the input/output value of a color channel? What is the
    source of the 'input' and what is the destination of the
    'output'?
    I have been imagining the input/output in the 'Levels' dialog,
    among others, as a kind-of before and after transform but apparently
    there is more to it than that.

    Thanks,
    Ron
