• 1

Which of the following gates is the OR gate?

• 
• 
• 
• 

What is this logic gate?

• NAND

• NOR

• XNOR

• XOR

What does the XOR gate do?

• If the two inputs are the same, the output is 0, but if the two inputs are different, then the output is 1. The twist is that the answer is reversed.

• If the two inputs are the same, the output is 0, but if the two inputs are different, then the output is 1.

• If the two inputs are the same, the output is 1, but if the two inputs are different, then the output is 0.

• It multiplies, then adds, then divides, then reverse... Basically it does every operation.
