Answer 4

False

Question 5

Fill in the blank: The ____ gate outputs true only when both inputs are false.

Answer 5

NOR

Question 6

What symbol represents an AND gate in a logic diagram?

Answer 6

A flat-ended shape with a dot at the output.

Question 7

Which logic gate is represented by a curved shape with two inputs and one output?

Answer 7

OR gate

Question 8

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

Answer 8

False

Question 9

True or False: A NOT gate can have multiple inputs.

Answer 9

To invert the input signal.

Question 11

Which logic gate is equivalent to an AND gate followed by a NOT gate?

Answer 11

NAND gate

Question 12

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

Answer 12

False

Question 13

Fill in the blank: The ____ gate outputs true if the inputs are different.

Answer 13

XOR

Question 14

What is the main use of logic gates in digital circuits?

Answer 14

To perform logical operations on binary data.

Question 15

Which logic gate can be used to create a multiplexer?

Answer 15

AND, OR, and NOT gates can be used together.

Question 16

True or False: A buffer is a type of logic gate that amplifies the input signal.

Answer 16

True

Question 17

Which logic gate can be used to implement a full adder?

Answer 17

AND, OR, and XOR gates.

Question 18

What is the function of a half adder?

Answer 18

To add two single-bit binary numbers and produce a sum and a carry output.

Question 19

Fill in the blank: The ____ gate produces an output that is true unless both inputs are true.

Answer 19

NAND

Question 20

What is the output of a NOR gate when at least one input is true?

Answer 20

False

Question 21

Which logic gate is often used for error detection?

Answer 21

XOR gate

Question 22

What is the truth table used for?

Answer 22

To represent the output of a logic gate for all possible input combinations.

Question 23

True or False: Logic gates can be combined to create complex circuits.

Answer 23

True

Question 24

What is a universal gate?

Answer 24

A gate that can be used to construct any other type of gate, such as NAND or NOR.

Question 25

Which logic gate has the highest number of inputs?

Answer 25

There is no maximum; it can depend on design, but NAND and NOR gates can have multiple inputs.
