The document discusses half adders, full adders, and 4-bit adders. A half adder adds two input bits and produces a sum and carry output. It does not account for carry from previous bits. A full adder adds three inputs - two bits and a carry - and produces a sum and carry output. It can be used to add multi-bit binary numbers. A 4-bit adder example is given to demonstrate adding two 4-bit binary numbers using full adders.

- 3. Half adder is a arithmetic circuit that adds two numbers and produces a sum bit (S) and carry bit (C) as the output The half adder can add only two input bits (A and B) and has nothing to do with the carry if there is any in the input That means the binary addition process is not complete and that’s why it is called a half adder HALF ADDERHALF ADDER
