I need help studying for computer programming gates, like drawings, truth tables?
Just remember the rules for each:





AND = both have to be TRUE


OR = at least one has to be true


XOR = one, and only one, are true


NAND = false only if both are true


NOR = true only if both are false


~ = changes T -%26gt; F, F -%26gt; T
