So I am having a really hard time understanding slotted and pure aloha. I have understood CSMA/CD fairly well, but that is it. I have the book: Computer networking - a top down approach, but I find the explanation very cryptic and hard to understand. Wikipedia did not help me. Does anyone have a brief "aloha for dummies" explanation? or perhaps a video tutorial? I think I need something visual. I don't need to be able to create the protocol, I just need a general understanding of it.
