Logic Gates

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

• 0

• true

• 1

• 1.5

How does an OR gate behave when at least one input is 1?

• The output is undefined.

• The output is 1.

• The output is 0.

• The output is always 1.

What is the result of a NOT gate when the input is 0?

• 1

• -1

• 2

• 0

Describe the characteristics of a NAND gate.

• A NAND gate outputs true only when one input is true.

• A NAND gate outputs true only when all inputs are false.

• A NAND gate outputs false only when all inputs are true; otherwise, it outputs true.

• A NAND gate has no effect on the output regardless of the inputs.

What does an XOR gate output when both inputs are the same?

• 0

• True

• 2

• 1

What is the output of a two-input OR gate when both inputs are 0?

• 1

• 0.5

• 0

• undefined

How does the output of a NOT gate change with its input?

• The output of a NOT gate is always high regardless of the input.

• The output of a NOT gate is always low regardless of the input.

• The output of a NOT gate is the same as its input.

• The output of a NOT gate is the opposite of its input.

What is the significance of a NAND gate in digital circuits?

• The NAND gate can only perform AND operations.

• The NAND gate is significant because it is a universal gate that can implement any digital logic function.

• The NAND gate is less efficient than a NOT gate.

• NAND gates are used exclusively in analog circuits.

What is the output of a NOR gate when both inputs are 1?

• 0

• 3

• 2

• 1

Explain the difference between an AND gate and an OR gate.

• An AND gate can have multiple true outputs, whereas an OR gate can only have one true output.

• An AND gate requires all inputs to be true for a true output, whereas an OR gate requires only one input to be true for a true output.

• An AND gate outputs true if at least one input is true, while an OR gate outputs true if all inputs are true.

• An AND gate requires no inputs to be true for a true output, while an OR gate requires all inputs to be true.
