Much of the background that you’ll need to know, is covered in this introductory lesson and the review lessons taught by Charlie Brubaker. However, to get the full benefit of this course, you should have a strong undergraduate background in computer systems and networks. With that in mind, let’s get started with our review and load some of the operating systems basics into our collective memories. I’ve intentionally structured this lesson to be quiz-heavy, since most of the background material should be already familiar to you. And hopefully that format that I’m going to use, we’ll find this to be a more fun way to jog our collective memories.
