Truth Tables and Logic Gates Quiz

What does a truth table show for a logic gate?

• The physical layout of the gate

• The history of the gate's invention

• The cost of building the gate

• All possible input values and their output values

Which statement best describes the AND gate?

• It outputs true if at least one input is true.

• It inverts the input value.

• It outputs true when both inputs are false.

• It outputs true only when all inputs are true.

In a truth table for an AND gate, what is the output when one input is 0 and the other is 1?

• 1

• It cannot be determined.

• 0

• It depends on the NOT gate.

In a truth table for an AND gate, what is the output when both inputs are 1?

• 1

• 0

• It depends on the NOT gate.

• It cannot be determined.

If an OR gate has inputs A = 0 and B = 1, what will the output be?

• It cannot be determined.

• It depends on the NOT gate.

• 1

• 0

How does the output of an OR gate behave with inputs A = 0 and B = 0?

• The output is 1.

• The output is 0.

• The output is unpredictable.

• The output is always true.

If you have an OR gate with inputs A = 1 and B = 0, what will the output be?

• 1

• 0

• It cannot be determined.

• It depends on the NOT gate.

What does a NOT gate do to its input?

• It outputs true only when all inputs are false.

• It requires all inputs to be true for output to be true.

• It inverts the input value.

• It combines inputs to produce a single output.

What is the role of the NOT gate in logic circuits?

• It combines inputs to produce a single output.

• It inverts the input value.

• It outputs true only when all inputs are false.

• It requires all inputs to be true for output to be true.

Which of the following best compares the AND gate and the OR gate?

• Both require all inputs to be true for output to be true.

• The AND gate outputs true only when all inputs are true, while the OR gate outputs true if at least one input is true.

• The OR gate inverts the input values.

• The AND gate can have any number of inputs.
