Ok,

Say I have 2 values. What does effect would an Exclusive OR function have on these 2 values? What would the output be?

Just got something I am trying to understand.

I understand that an OR function can have 2 inputs and either of the inputs being "on" will trigger an output and that an Exclusive OR means one or the other but not both will trigger an output, but I'm not sure how this would apply when talking values opposed to input signals.

Anybody care to comment?
