What is the output of an AND gate if both inputs are 1?

• 1.5

• undefined

• 1

• 0

How does an OR gate function with one input as 0?

• The output will be 1 if both inputs are 0.

• The output will always be 1 regardless of the other input.

• The output will be 1 if the other input is 1; otherwise, it will be 0.

• The output will be 0 if the other input is 0.

What is the primary characteristic of a NOR gate?

• The output is true when all inputs are true.

• The output is true only when all inputs are false.

• The output is true when at least one input is true.

• The output is false only when all inputs are true.

Describe the output of an XOR gate when both inputs are the same.

• 2

• True

• 0

• 1

What does a XNOR gate output when the inputs differ?

• True

• 1

• High

• 0

Explain the function of a NAND gate in simple terms.

• A NAND gate outputs true only when both inputs are true.

• A NAND gate has no effect on the inputs and simply passes them through.

• A NAND gate outputs true unless both inputs are true.

• A NAND gate always outputs false regardless of the inputs.

What is the truth table for a basic AND gate?

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

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

• | 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 | 0 | | 1 | 1 | 1 |

What is the output of a NOR gate if at least one input is 1?

• 1

• 2

• undefined

• 0

What is the difference between XOR and XNOR gates?

• XOR and XNOR both output true for the same inputs.

• XNOR outputs true for different inputs; XOR outputs true for the same inputs.

• XOR outputs true for all inputs; XNOR outputs false for all inputs.

• XOR outputs true for different inputs; XNOR outputs true for the same inputs.

In what scenario does a NAND gate output a 1?

• A NAND gate outputs a 1 only when both inputs are 1.

• A NAND gate outputs a 1 when both inputs are 0.

• A NAND gate outputs a 1 when at least one input is 0.

• A NAND gate outputs a 1 when at least one input is 1.
