DIGITAL CIRCUITS
Logic Gates are digital circuits. All digital circuits are either ON or OFF.

A light switch in your house can be used as an example of a digital circuit. The light is either ON or OFF depending on the switch position.

When the Light is ON the output value is '1'.

When the Light is OFF the output value is '0'.

The inputs are the position of the light switch. The switch is placed either in the ON or OFF position to activate the Light.
