one thing that has always miffed me is how is it that the hardware carries out the coded instruction. the code is 1's and 0's, and if I have understood anything. 1's and 0's are on and off. but how is the computer flipping the circuits on and off? something must tell it to do that. but then what is telling it to follow those instructions. etc. I am unfamiliar, but have friends to took circuits or logic circuits or something like that, and so I guess at the most basic level, logic circuits are used in a magical way to control everything. all code must carry with it instructions that activate those circuits? I don't know. it's weird to me. almost as if there must be a brain in there deciphering the code and carry out the orders.
