Boolean logic

Question 2

What is Boolean logic?

Answer 2

A form of algebra that uses true/false values to perform logical operations.

Question 3

True or False: The primary values in Boolean logic are 0 and 1.

Answer 3

True

Question 4

What are the three basic operations in Boolean logic?

Answer 4

AND, OR, NOT

Question 5

Fill in the blank: In Boolean logic, the AND operation returns true if _____ operands are true.

Answer 5

both

Question 6

What does the OR operation do in Boolean logic?

Answer 6

It returns true if at least one operand is true.

Question 7

True or False: The NOT operation inverts the truth value of its operand.

Answer 7

True

Question 8

What is the result of the expression TRUE AND FALSE?

Answer 8

FALSE

Question 9

What is the result of the expression TRUE OR FALSE?

Answer 9

TRUE

Question 10

A NAND gate is a combination of which gates?

Answer 10

NOT - AND

Question 11

What is a truth table?

Answer 11

A table that shows all possible truth values for a set of Boolean variables.

Question 12

True or False: A truth table can only represent two variables.

Answer 12

False

Question 13

How many inputs does the NAND gate have?

Answer 13

The NAND gate only has one input

Question 14

What is the result of the expression NOT (TRUE AND FALSE)?

Answer 14

TRUE

Question 15

What is an NAND gate?

Answer 15

Reversers the output of an AND gate

Question 16

What is a NOR gate?

Answer 16

Reversers the output of an OR gate

Question 17

True or False: The commutative law states that A AND B = B AND A.

Answer 17

True

Question 18

What is an XOR gate?

Answer 18

It works similar to an OR gate except it is false if both the inputs are true. In a circuit diagram it has the extra line at the back of the shape.

Question 19

Fill in the blank: In Boolean logic, the exclusive OR (XOR) operation returns true if _____.

Answer 19

exactly one operand is true

Question 20

What is a logical gate?

Answer 20

An electronic circuit that performs a Boolean function.

Question 21

True or False: NAND is the negation of the AND operation.

Answer 21

True

Question 22

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

Answer 22

TRUE

Question 23

Fill in the blank: The _____ gate only produces an output when both inputs are true.

Answer 23

AND

Question 24

What is the significance of Boolean logic in computer science?

Answer 24

It is used in programming, circuit design, and algorithms.

Question 25

True or False: Boolean logic can be applied to more than just true/false values.

Answer 25

False

Question 26

What does a half adder do in digital circuits?

Answer 26

It adds two single binary digits and provides the sum and carry output.

Question 27

What is the primary use of a multiplexer in Boolean logic?

Answer 27

To select one of many input signals and forward the selected input into a single line.
