its bcoz all other gates lik AND,OR,NOT,XOR...........etc.u can achieve the functionality of these gates with the help of NAND and NOR.u can replace all these gates in a circuit wit the help of NAND...
Nand, Nor, And, and Or gates are the most commonly used logic circuits. We also have XAnd, Xor and Inverting gates.Most electronic components producers make variations of these gates but their...
NAND AND NOR gates are called universal gates , becaus with a combination NAND and NOR gates alone, it's possible to create all other logic gates like AND, OR, XOR etc and you can design any logic...
