may be my question was asked earlier but i want info away from logical abstractions, in different contrast. START: a transistor can represent two states on and off means 1 and 0 means 1bit. so why we dont use only 32 transistors to represent a 32bit data. why there are logic gates which contains normally 2-8 transistors in each to represent 1 bit only in each gate, which commonly input 2 bits and output 1 bit. what type of input bits they are and why only one output then how we use that one output furthur, why we degrade 2 bit to one. END summary: I need a very lowest possible physical structure of cpu starts from a transistor to assembly, without any abstract terminologies. I read many tutorials on the web but i could nt understand. that why iam here.
