Using NAND or NOR gates to make up Circuits

All other gates/functions can be implemented by NOR or NAND gates. so they are called universal gates. In fact, in chips, entire logic maybe built using only NAND (or NOR) gates.

eg:
inverter— nand with inputs shorted.
and —— nand followed by a inverter(using nand).
or——— giving inverted inputs to nand gate.
