what is binary adders



Binary adders are digital circuits that add binary numbers in either binary or binary coded decimal (BCD) format. These devices are typically used in arithmetic logic units (ALUs) and registers. There are two types of binary adders: half adders and full adders. Half adders can add two binary digits or bits. Full adders can add three binary digits or bits. The binary addition of two bits produces two numbers: the sum of the added bits and a carryover bit that is then added to the next column in the flow. Both half adders and full adders have two inputs, one for each added bit, and a single output for the sum of the added bits. Only full adders also have an additional output for handling the carryover bit.
