True or False: The expression A AND B is true if A is true and B is false.

Answer 8

False

Question 9

What is a truth table?

Answer 9

A truth table is a mathematical table used to determine the output of logical expressions based on their inputs.

Question 10

What is the output of the expression TRUE OR FALSE?

Answer 10

TRUE

Question 11

What is the output of the expression NOT TRUE?

Answer 11

FALSE

Question 12

Fill in the blank: The result of A OR B is false only if both A and B are ______.

Answer 12

false

Question 13

What is the purpose of Boolean Logic in computer science?

Answer 13

Boolean Logic is used to create conditions and control the flow of programs.

Question 14

True or False: Boolean values can only be true or false.

Answer 14

True

Question 15

What is the result of the expression (A AND B) OR (NOT A)?

Answer 15

The result depends on the values of A and B.

Question 16

What does De Morgan’s Theorems state?

Answer 16

De Morgan’s Theorems state that NOT (A AND B) is equivalent to (NOT A) OR (NOT B), and NOT (A OR B) is equivalent to (NOT A) AND (NOT B).

What is the output of the expression FALSE OR FALSE?

Answer 21

FALSE

Question 22

What does the NOT operation do to a Boolean value?

Answer 22

The NOT operation inverses the value: it turns true to false and false to true.

Question 23

True or False: In Boolean Logic, (A OR B) AND (A OR NOT B) is always true.

Answer 23

True

Question 24

What is a logical expression?

Answer 24

A logical expression is a combination of Boolean variables and operations that evaluates to true or false.

Question 25

True or False: Boolean Logic is not used in programming languages.

Answer 25

False

Question 26

What is the significance of Boolean Logic in digital circuits?

Answer 26
