What I hope to find out in this class

I cannot think of one burning question I have for this class, but a couple areas I would lik to know more about include the actual monitor and how video is shown, and how the computer is able to store so much memory. I've wondered how graphics can be presented so well on the computer, especially when watching a movie or playing a game. It also surprises me that computers are able to store so much information, while their actual insides are extremely small. I'd like to know more about both these concepts.
