it is logic gate, any input is low then output is high.

single word : compliment of and gate

NOR Gate :
it is logic gate, any input is high then output is low.

single word : compliment of or gate.

XOR Gate :

it is a logic gate, which performs exclusive or operation.

single word : output is high only when two inputs different.

XNOR Gate :
it is a logic gate, which performs exclusive nor operation.
