ive been working on a long (about 15 pages so far?) explanation of how computers work, mostly in laymens terms, starting with a justification that all computers (phones, laptops, mainframes) consist essentially of:
* switches (cpu, processors, ram, usb sticks)
* lights (crts, actual mini lamps, lcd, leds)
* sensors (keyboards, touchscreens, touchpads, mice)
* wires (and why radio should be in this category)
* tapes (paper tape, magtape, disks, optical media)
and how they work together to produce what we call "computing."
i also talk about interfaces, with user interfaces as an example, an how to the computer it doesnt care if its talking to the user or to another computer, it does interfaces the same way: all with numbers.
and the relationship between numbers and everything else from colors to addresses to instructions to various inputs and outputs. call it a "unified computing theory" for people that think of the computer as a magic thing. im also working on fig os.
