Document Summary

Cs 105 intro into computing: non-tech - unit 2. Types of logic: both math and philosophy are roots of cs. Does not worry about whether an argument is good or bad, but rather whether it is true or fale. Calculus ratiocinator - used logical symbols to make calculation relating to human thought. Binary: expressing in terms of 0 (zero) and 1 (one) Symbolic logic and the boolean algebra that are fundamental to modern computing systems (ignoring quantum computing) Boolean algebra has variables that are truth values (true or false_ If you have two circuits you have to have a beginning and. Processor - the brain has a fixed set of instructions it can execute . Example sparc - a specific part of architecture in computers. Move to an instruction at a specific address in memory. Save/load from a specific address in memory. Executing very specific sequences of steps repeatedly. Seeing the world through a computer scientists eyes.
