what is logic gates?
A digital circuit which one or more input signals but only one output signal is called Logical gates.
Since a logic gate is a switching circuit (i.e. a digital circuit), its outputs can have only one of the two possible states viz. either a high voltage (1) or a low voltage(0) - it is either ON or OFF. Whether the output voltage of logic gate is high (1) or low (0) will depend upon the condition at its input.
