Lesson 1: Binary numbering

Lesson 1: Binary numbering

(gentle music) - [Instructor] Welcome to lesson one of module two, where we're going to be focused on binary numbering and understanding binary is more than just academic. It is essential for configuring network addresses, performing subnetting calculations, and even doing troubleshooting. Now, here's what you're going to be learning in this lesson. You're going to learn how to convert from binary numbers to decimal and vice versa. You'll convert from decimal to binary. You'll learn how to do both of those conversions in our next video, and that's going to be followed by a couple of videos where I'll challenge you to practice your binary skills, where you'll be converting from binary to decimal and decimal to binary, and mastering the skill is going to come in super handy later in this module as we get into subnet calculations. Now, let's get started in our next video with an introduction to binary numbering.
