# XOR gate

 > `XOR` stands for **exclusive or**, also known as **exclusive conjunction**. This means it can only be `true` if one of its propositions are `true` . If both are `true` this doesn't exclude one of the propositions so the overall statement has to be `false` . This is the only change in the truth conditions from `OR` .
