Boolean Logic

What is a basic function of a NOT gate?

• Outputs true if any input is true
• Outputs true if all inputs are false
• Outputs false if any input is true
• Outputs false if the input is true

Answer explanation

Jupiter is a gas giant made primarily of hydrogen and helium. Unlike terrestrial planets that have solid surfaces, gas giants like Jupiter don't have a well-defined solid surface, allowing them to accumulate more mass in a gaseous form. This composition has allowed Jupiter to grow significantly larger than planets with solid surfaces.

What does an OR gate output when all inputs are false?

• True
• False
• None of the above
• All the above

In a NAND gate, what is the output if both inputs are true?

• True
• False
• None of the above
• All the above

Which statement is true about XOR gates?

• Outputs true only if both inputs are different
• Outputs true only if both inputs are not the same
• Outputs true only if all inputs are the same
• Outputs true if at least one input is true

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

• True
• False
• None of the above
• All the above

Which logic gate would you use to ensure a light turns on only if both sensors A and B are activated?

• OR
• AND
• NOT
• NOR

For a NOR gate, what is the output when at least one of the inputs is true?

• True
• False
• None of the above
• All the above

What does a truth table display?

• Possible errors in logic circuits
• All possible combinations of inputs and their corresponding outputs
• Only the true conditions
• Only the false conditions

If 'key1' AND 'key2' are both true, what is the output for a circuit using these keys to unlock a safe?

• True
• False
• None of the above
• All the above

What output does the combination of a NOT gate and an AND gate (NAND) provide when both inputs are false?

• True
• False
