The logic gates is basic building blocks of electronics logic circuits for large circuit its is more complex and no of logic gates is increase. These logic gates perform a basic Boolean functions, such as AND, OR, NAND, NOR, Inversion, Exclusive-OR, Exclusive-NOR. Boolean function, and truth. It is seen from the Fig that each gate has one or two binary inputs, A and B, and one binary output, C.

The different types of logic gates are:
NOT GATE
AND GATE
OR GATE
NAND GATE
XOR GATE
NOR GATE
XNOR GATE
