You should take this course if you want to have mastery over the foundations of digital technology... if you want to look at an HD movie and think "I know how that's working on the root level. Awesome!" This course is all about binary, hexadecimal, and the core concepts that make all of our modern information technology possible. There are videos, quizzes, and a couple of App Cat episodes in presentation format. You should watch the videos in order. Some of them build on the content from the last video. There are 3 chalkboard session videos that show the how-to steps for reading and writing binary and hexadecimal. You should watch those with paper and a pencil. You'll want to follow along.
