What are the three fundamental operations in Boolean Algebra?

• NOT, OR, XOR

• AND, OR, XOR

• NOT, AND, OR

• AND, OR, NOT

What does a NOT gate do?

• Takes two boolean values and returns true if both are true

• Takes two boolean values and returns true if at least one is true

• Takes a single boolean value and negates it

• Takes a single boolean value and returns true if it is true

How can an AND gate be built using transistors?

• By connecting two transistors in series

• By connecting two transistors in parallel

• By connecting a transistor and a NOT gate

• By connecting a transistor and an OR gate

What is the output of an OR gate if both inputs are false?

• True

• False

• Depends on the specific circuit

• Cannot be determined

What is the purpose of an XOR gate?

• To perform addition of binary numbers

• To perform subtraction of binary numbers

• To perform multiplication of binary numbers

• To perform exclusive OR operation

What is the symbol used to represent an XOR gate?
