Document Summary

Chapter 9 apps/software isn"t so hard/instruction execution engine/translation/integrated circuits. There"s an app for that: principles of computation. Usual suspects: the processor device that does the actual computing. It does the work, that is, follows programs instructions (aka computer, microprocessor, central processor, cpu (central processing unit) and core: the operating system (os) software that makes the computer (processor) into a useful device. Transistors and silicon chips that implement the bits. Make one typo and the program has a bug values like fadeout. Deciding on what to dot: testing and acting on the outcomes is very common algorithms, so all languages have an instruction called if. It asks true/false question: the actual test question is in the parentheses following the word if; the rest of this code says what to do based the outcome, opacity how transparent it is. Software layers: software stack , because a given layer is built with code from the levels below, they are organized from more.
