Basic gate NOR is equivalent to two open switch mounted parallel / row.

Will happen outputs “1” when all the switches A = “0” or B = “0”. NOR gate is equal to the OR gate installed in series with a NOT gate.

Exclusive OR (EX-OR)
EX-OR gate is often written with the X-OR gate is most often used in computer engineering. EX-OR gate will only have output Q = “1” if inputs A and B have different conditions. At 3:19 the picture which is a picture of the electrical equivalent circuit EX-OR shown that when the switch A and B respectively disconnected (off), then the light will die. When the switch A and B each connected (on), the lamp is also dead.
When the switch A is connected (on) while the switch B disconnected (off), then the light goes on. Vice versa if switch A is disconnected (off) and switch B is connected (on) then the light goes on. So that it can be concluded that the lights will be lit only when the condition of the switch A and B opposite. Signs in pelunilsa EX-OR is the mark

EX-NOR gate (exlusive-NOR)
In picture 21 is equivalent to the electrical circuit EX-NOR gate. When the switch A and B each connected (on) or disconnected (off) then the light goes on. However, when the switch A and B in the opposite condition, then the light will die. So that it can be concluded that the EX-NOR gate will only have output Q = “1” if inputs A and B have the same condition. Electrical circuits :
