HALF ADDER – A “littleBit” of Arithmetic


Half Adder

At the very least, one would expect that any computer should be able to add two numbers. With the logic modules this becomes a reality! We humans think in decimal—base ten, with digits 0 through 9—probably as a result of the fact that we have ten fingers. Computers, on the other hand, do all of their internal work in binary—base two, with the digit 0 representing OFF and 1 representing ON. In this lesson, you will learn how to create a circuit that can add two bits. This circuit is known as a HALF ADDER.
