Which statement is true about a NOT gate?

Which statement is true about a NOT gate?

• A. It produces the sum of inputs.
• B. It has two inputs.
• C. It has a single input.
• D. It is not used in digital circuits.

Answer: (C)

A NOT gate is an inverter in digital logic, used to flip a bit. It has a single input, so it can only operate on one value at a time. Its job is to produce the opposite of what is fed in: if the input is 0, the output is 1, and if the input is 1, the output is 0. It does not sum inputs, and it isn’t defined by having two inputs. NOT gates are fundamental in digital circuits and are widely used to build more complex logic.
