Characters on a piece of paper are symbols represented by inky marks. '1's and
'0's in a computer are symbols represented by electrical voltage (sometimes).
You have it reversed.
If you put a logic probe on an AND gate pin it will tell you what the logic
convention is for the voltage at that pin. However, if you use inverted logic in
your circuit, then the logic probe result will be wrong. Use a voltmeter and
decide for yourself what the voltage symbolises in your circuit. People resolve
electrical values into symbols and not computers.
Processors cannot resolve symbols. That is one of those abstract programmey
things. Just like deciding that the electrical voltage that represents a logical
value 'Yes' or 'On' also represents a numerical value of '1' and does not
represent any character value 'cos they need a bunch of at least eight bits.
[That person shouting IA5, please shut up!]
Processors cannot process lookup tables or symbolic references. They can do
arithmetic, load and save binary values from and to memory and jump to an
out-of-sequence block of machine code on the basis of the results of the
arithmetic or a machine code instruction in memory. Apart from whizzy specialist
instructions that is all they can do, Some of them get clever with indirection,
but that is just embellishment of the basics.
Resolving references is just something that programmers can do using the basic
capability of microprocessors.
