There really isn't anything that can really teach you about computers unless you actively invest some time and get hands on or actively participate in discussions. Reading through walls of text will help you with what they are and how they come to be, but other things such as using it, unlocking certain features, tricks, etc.. aren't readily available unless you search for it specifically.
