NOT Gate

A NOT gate is a basic digital device that reverses the input signal. If the input is on (represented by a 1), the NOT gate output turns off (produces a 0). Conversely, if the input is off (0), the output turns on (1). It's like a simple switch that flips the state: one state becomes the opposite. NOT gates are fundamental components in electronic circuits, used to invert signals and help perform logical operations essential for computing and digital systems.
