I have been working with this sort of thing for a while now, and, often, as an introduction, compare the pixels of a digital to analogue camera. The thing is, this is nearly first generation technology compared to fiftieth generation - you can honestly see how a glass lens camera give better pictures than a digital one, as, there are no pixels, yes? This will be where the pixels are basically photon size!
The problem with that and other types of analogue systems is rendering them - 'the getting the best out.' This could be made easier by taking the camera and making the scope into a few overlapping screens - this would be like binary for the digital camera, except that it would be 'error checking,' yes? So far so good...
Then, we need to observe that a computer or electronic device would operate better with the added 'error checking.' This would also result in the electronic device processing at the speed of electricity, where the bus would operate at the 'maximum allowed speed,' of course. This would be natural, so would not tweak the circuit board to over clock, where the board would simply transmit like a radio, yes? This could be sped up, naturally, by using magnets, of course.
