Understanding Logic Gates

What is the primary function of a transistor in a computer?

• To enhance graphical performance

• To store large amounts of data

• To serve as a small light switch

• To act as a miniature speaker

What is a NOT gate primarily used for?

• To store data

• To invert the input signal

• To multiply inputs

• To add numbers

When using an AND gate with inputs A and B, what output is produced if both A and B are '1'?

• 10

• 2

• 0

• 1

Which of the following gates will output a '1' if at least one of the inputs is '1'?

• AND gate

• OR gate

• NOT gate

• NAND gate

What is the output of a NAND gate when both inputs are '0'?

• 1

• 2

• 0

• 4

The exclusive OR (XOR) gate outputs a '1' when:

• Both inputs are the same

• Both inputs are '0'

• One input is '0' and the other is '1'

• Both inputs are '1'

What does the exclusive NOR (XNOR) gate do?

• Outputs '1' when inputs are different

• Inverts the output of an AND gate

• Outputs '0' only

• Outputs '1' when both inputs are the same

Which of the following statements about logic gates is true?

• They are the foundation of computer circuits

• They cannot combine with each other

• They can only perform addition

• They are only used in basic calculators
