can anyone please suggest me any good book or notes to for computer organization and architecture for beginners having no knowledge of computer science
It matters why you want to know in order to give you the best advise. Like if you wanted to know how the common PC worked or if you wanted something more generic, like what might be found in a textbook. Without knowing more, I'd suggest you go to Wikipedia and just search for the key words, or even just search the internet. Or describe what your goal is or why you want this knowledge.
As already pointed out, it depends on what you are trying to get out of it. If you could describe that better, I might be able to make a recommendation. I have about three in mind, but they are for very different audiences.
