What is a truth table in Boolean algebra used for?

• To organize mathematical equations
• To list all possible input and output combinations of logical operations
• To draw circles and lines
• To decode secret messages

The output of an AND gate is 1 only if both inputs are 1.

What is the output of an OR operation if both inputs are 0? (Enter 1 or 0)

• 0

How many possible output rows will a truth table have for two input variables?

• 2
• 4
• 6
• 8

In Boolean algebra, the symbol '+' is used to represent the AND operation.

What is the result of the NOT operation on input 0? (Enter 0 or 1)

• 1

Which combination shows a TRUE (1) output for an AND gate?

• Input A = 1, Input B = 1
• Input A = 1, Input B = 0
• Input A = 0, Input B = 1
• Input A = 0, Input B = 0

A truth table can be used to simplify complex Boolean expressions.

What is the output of an OR gate if at least one input is 1? (Enter 1 or 0)

• 1

If a truth table for a circuit shows all outputs as 0, what type of function does it represent?

• Constant 1 function
• Constant 0 function
• OR function
• XOR function
