NAND gates: The NAND gate, often known as the "NotAND" gate, is a combination of the AND and NOT logic gates.
A combination of the NAND and NOR gates can be used to perform any of the basic operations, they are known as universal gates.
Full adder: A full adder circuit serves as the brain of the majority of digital circuits that perform addition or subtraction.
Draw the required diagram of full adder using and gates.
Its name comes from the fact that it produces a total and a carry-out digit by adding two binary digits plus a carry-in number.
A full adder necessitates the use of nine NAND gates.
The ALU, or arithmetic logic unit, uses full adders. In a computer, full adders are used by the ALU to create memory addresses and move the Program Counter to the next instruction.
