Field Guide to Binary

Binary and all alternate numbering systems work in the same ways as the decimal system. In this course, you'll explore binary and hexadecimal, and transition through alternate numbering systems to strip away the magic.

Are you familiar with binary numbers but don’t know precisely what they are, or how they work? In this course, Field Guide to Binary, you'll dive into the fundamental concepts of binary using the math you’ve always known. First, you'll explore the decimal (base 10) numbering system. Next, you'll discover exactly how to translate from binary to decimal. Finally, you’ll learn why Unicode and RGB color values use those unique sequences of numbers and letters. By the end of this course, you'll have the fundamental knowledge necessary to demystify binary and hexadecimal in your everyday work.

Course Overview
Hi, this is Tod Gentille. I'm in sunny southern California. I don't know where you are, but I know you're watching the Field Guide to Binary. If you can give me 20 minutes, you're not going to just learn binary, you're going to learn that all alternate numbering systems work the same way as the decimal system that you've grown to know and love. So stick around. Investing some time in learning how alternate numbering systems, like the base 8 octal system or the base 16 hexadecimal system work, will help you more fully understand some surprising things. For example, aircraft transponders transmit a four digit octal number, while that might only interest air traffic controllers, a little closer to home, you'll find octal showing up in Unix-based operating systems, like Linux and Mac OS, when you set permissions for files. You'll see hexadecimal values in almost any program you use that lets you set colors. If you aren't a programmer, you won't likely come across binary in the wild, but knowing how it works will help cement all the alternate numbering systems that you will see. If you do program, having a good understanding of binary can be quite useful. In this course, we're going to start right in your comfort zone and talk for a few minutes about decimal, or the base 10 numbering system. Once we have some basic math under our belts, we'll transition briefly to octal, but only to help ease our way to binary. We'll translate from binary to decimal and even learn that adding binary numbers works the same as adding decimal numbers. If you do the exercises as we go through the course, you'll unlock the magic and demystify binary and hexadecimal. You won't need a potion or wand, your subscription to Pluralsight and 20 minutes is all that's required. Let's get started.
