Quote: In the binary system only two symbols are needed to represent information (a number or letter). Every number or letter can be expressed as a series composed of 1s and 0s. At the very heart of electronic binary these 1s and 0s can mean the existence or absence of an electronic pulse. 1s can be thought of as "on" or "positive" and 0s can be thought of as "off" or "negative". Obviously the binary system is extremely powerful as it used to compute every single process on your computer. With binary we can perform cool operations using methods such as masking, 2s compliment and gate circuiting which you'll learn in part 2 of this series. For now we will focus on the most basic binary operations such adding and subtraction of two binary strings.
One thing to get down is that in the computer world these binary digits (1s and 0s) are also called bits and eight of these bits is a byte. We will start out our addition operations using 4 bits or a half a byte. Just the Boolean logic key below to follow along. | Read more... http://physicspost.com/articles.php?articleId=41 |
