> In a nutshell, what you are reading is intended to be a shop class for computer science. Young computer science students are taught to "drive" the computer; but where do you go to learn what is under the hood?
I take that to mean this guide is a supplement. A student would already know what a bit is.
"instead of being stored as bits on a disk the information is displayed as dots on a screen"
But the concept of bits has not been introduced.
