What is the output of an AND gate when both inputs are true?
False (0)
True (1)
Undefined
Error
What does a NOT gate do to its input?
Doubles the input
Outputs the same value
Halves the input
Inverts the input
When will an OR gate output a true value?
When at least one input is true
When both inputs are false
When both inputs are true
When all inputs are false
What is the function of a NAND gate?
Outputs false if any input is true
Outputs true if at least one input is false
Outputs true unless all inputs are true
Outputs true only if all inputs are true
What is the output of a NOR gate when at least one input is true?
True (1)
False (0)
Undefined
Error
What does an XOR gate output when both inputs are the same?
Undefined
True (1)
Error
False (0)
What is a truth table used for?
To represent outputs of logic gates

What is the primary difference between an AND gate and an OR gate?
AND gate outputs true only if all inputs are true
OR gate outputs true only if all inputs are true
AND gate can have more inputs than OR gate
OR gate outputs false if any input is true
