Well, I want learn how the computer works and for understand all about computer I decided make one, I see this site: www.mycpu.eu and it's very complete but he isn't explains the electronic foundations and physicists of what he has done to construct his computer (he not explains how he has designed every part of the components). Because I want to learn, though it may be of basic form, how it is designed (including all kinds of calculations) every piece and my final aim is to know as a computer "knows" for example 011111010101011 it means to "save a file", and it not mean " reproduce this song ". Do not be if understand me. Can somebody help me? lool :D Sorry for my bad english, I only want learn.
