Thanks for replying to my question with negative reputation, that totally makes me want to continue helping you. :rolleyes:
The "topic" you want is basically the whole of computer science and engineering, so you're not going to find a single source of information. You need to pick a specific topic and then search for that, then pick another specific topic and search for that. Just searching for "computer organization" will get you results, but not terribly useful results if you're expecting some sort or brain dump of everything there is to know.
