Understanding Logic Gates

What is the output of an AND gate if both inputs are true?

• true

• false

• undefined

• not applicable

How does an OR gate operate when one input is false?

• The output will be false if the other input is true.

• The output will be true if the other input is true; otherwise, it will be false.

• The output is true only if both inputs are false.

• The output is always true regardless of the inputs.

What is the function of a NOT gate?

• The function of a NOT gate is to combine multiple input signals.

• The function of a NOT gate is to pass the input signal unchanged.

• The function of a NOT gate is to amplify the input signal.

• The function of a NOT gate is to invert the input signal.

What is the output of a NAND gate when both inputs are true?

• undefined

• true

• false

• high

How does a NOR gate behave when at least one input is true?

• The output is undefined.

• The output is true.

• The output is false.

• The output is always high.

In what scenario does an XOR gate output true?

• When both inputs are false.

• When both inputs are true.

• When at least one input is true.

• When exactly one input is true.

What is the truth table for an AND gate?

• | A | B | Output | |---|---|--------| | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 1 |

• | A | B | Output | |---|---|--------| | 0 | 0 | 1 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 0 |

• | A | B | Output | |---|---|--------| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 |

• | A | B | Output | |---|---|--------| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 1 | | 1 | 1 | 1 |

How many inputs can an OR gate have?

• An OR gate can have a maximum of five inputs.

• An OR gate can only have one input.

• An OR gate can have multiple inputs, commonly 2 to many.

• An OR gate can have exactly three inputs.

What is the output of a NOT gate if the input is true?

• null

• true

• false

• undefined

What is the difference between an OR gate and an XOR gate?

• The OR gate outputs true for any true input; the XOR gate outputs true only for one true input.

• The OR gate requires both inputs to be true; the XOR gate requires both inputs to be false.

• The OR gate outputs false for any true input; the XOR gate outputs true for all inputs.

• The OR gate outputs true only for one true input; the XOR gate outputs true for any true input.
