The Pictures I Draw When Teaching the CompTIA Security+ Test Prep CourseLearning Tree
These are the pictures I draw when I teach Learning Tree's Security+ test-prep course. I saved the pictures when I taught the course recently. Unless you were in that specific course run, these aren't exactly the same files, but I always draw pretty much the same pictures, and make the same lists, every time I teach the course.
These are GIF images. Right-click and select "Save image as..." to save them to your computer.
For some of them, it will be very helpful for you to be able to draw your own version. Just looking at them won't be nearly as helpful. Drawing your own version really helps you to learn what's going on. I'm thinking especially of the cryptography ones, as CompTIA likes to ask questions about which key is used first (or by the sender), which key is used last (or by the receiver), and other things that you can visualize with the flow in the picture.
Let us know how you did! Especially let us know if there were any surprises on the exam, any questions on topics we don't yet realize we need to cover.
