More about (11) So why is Digital better? Multiplexing explained

Basically if you can describe the system you want to build with an equation (often called an "Algorithm") you can either wire up the entire equation using miscellaneous electronic components, or you can build a standard piece of electronics (called a "Microprocessor") which "multiplexes" its way through the circuit very quickly, pretending to be each piece in turn, storing the current state, and then hopping to the next piece of circuit ("Instruction code" or "opcode") and then being that, and so on. Something like a roulette wheel spinning very fast appearing to show all the numbers at the same time. After all, why have lots of different things when you can build one very fast thing which can jump into the places of the other things and play their roles in quick succession? Plus, if you want to change its behaviour, you can just "reprogram" the one thing instead of changing a lot of other things around it.
