Which gate is the inverter that outputs the opposite of the input?

Explanation:
Inversion happens with a NOT gate: it takes a single input and outputs the opposite logic level. If the input is high, the output is low, and if the input is low, the output is high. That’s exactly what an inverter does. The other gates combine inputs in different ways (AND requires all inputs high to output high; OR outputs high if any input is high), and NAND is simply the inverse of an AND operation on two inputs, not a direct single-signal inverter.
