Fun with Logic Gates

What does an AND gate do?

• An AND gate outputs true if at least one input is true.

• An AND gate can have only one input.

• An AND gate outputs false only if all inputs are false.

• An AND gate outputs true only if all inputs are true.

If both inputs are true, what is the output of an AND gate?

• false

• null

• undefined

• true

What is the output of an OR gate if one input is true?

• true

• false

• undefined

• null

What does a NOT gate do to an input?

• It outputs the same value as the input.

• It doubles the input value.

• It inverts the input value.

• It adds one to the input value.

If the input to a NOT gate is true, what is the output?

• false

• null

• undefined

• true

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

• true

• false

• undefined

• high

How does a NOR gate work?

• A NOR gate outputs false only when both inputs are true.

• A NOR gate outputs true when both inputs are true.

• A NOR gate outputs true when at least one input is true.

• A NOR gate outputs true only when both inputs are false.

What is the output of a NOR gate if both inputs are false?

• true

• 1

• undefined

• false

What does an XOR gate do?

• An XOR gate outputs true only when both inputs are true.

• An XOR gate outputs true if the inputs are different.

• An XOR gate always outputs false regardless of the inputs.

• An XOR gate outputs true if both inputs are the same.

If both inputs to an XOR gate are the same, what is the output?

• True

• High

• 0

• 1
