3. Label the different gates
AND OR
NOT
XOR

4. Draw a line from the right definition to the the right logic gate
Either input needs to be on but not both to get it to work
AND
Exactly opposite to the input OR
Either input needs to be ON or both to work
NOT
Both inputs must be on to work
XOR

5. AND Truth Table ExampleC ON
Monitor ON
OFF
