Document Summary

The flow of electricity is controlled carefully: methods used to describe behaviours of gates + circuits: boolean expressions, logic diagrams, truth tables, boolean expressions: george boole invented algebra form where variables and functions only take on values of 1 or 0, logic diagram: graphical representation, each type of gate represented by a specific graphical symbol, truth table: defines function of gate by listing all possible input combos that the gate could encounter along with the output. If both inputs are 0 then output is 0all other cases output is 1: xor gate: aka exclusive or gate, produces 0 if both inputs are the same all other cases produces a 1 so xor and or only differ in 1 situation, nand gate: accepts 2 input values, opposite of and gate (ands inputs are nands outputs and vice versa, nor gates: accepts 2 input values, opposite of or gate (or"s inputs are nors outputs and vice versa)
