The flip side of this is that any information that can be reduced to a choice among two or more possibilities can be expressed using bits. Needless

a digital design engineer, you would spend long hours going through the TTL Data Book familiarizing yourself with the types of TTL chips that were available. Once you knew all your tools, you could actually build the computer I showed in Chapter 17 out of TTL chips. Wiring the chips together is a lot easier than wiring individual transistors

Code: The Hidden Language of Computer Hardware and Software Quotes

You’re twelve years old. One horrible day your best friend’s family moves to another town. You speak to your friend on the telephone now and then, but telephone conversations just aren’t the same as those late-night sessions with the flashlights blinking out Morse code. Your second-best friend, who lives in the house next door to yours, eventually becomes your new best friend. It’s time to teach your new best friend some Morse code and get the late-night flashlights blinking again.

Just as Morse code provides a good introduction to the nature of codes, the telegraph provides a good introduction to the hardware of the computer.

In the same way that Morse code reduces written language to dots and dashes, the spoken version of the code reduces speech to just two vowel sounds. The key word here is two. Two types of blinks, two vowel sounds, two different anything, really, can with suitable combinations convey all types of information.

Xamarin.Forms allows you to be as platform-independent or as platform-specific as you need to be. Xamarin.Forms doesn’t replace Xamarin.iOS and Xamarin.Android; rather it integrates with them.

Bits also play a part in logic, that strange blend of philosophy and mathematics for which a primary goal is to determine whether certain statements are true or false. True

We don’t carry in subtraction, however; we borrow, and that involves an intrinsically different mechanism—a messy back-and-forth kind of thing.

Code: The Hidden Language of Computer Hardware and Software Quotes

Today’s computers use transistors. When used in computers, transistors basically function the same way relays do, but (as we’ll see) they’re much faster and much smaller and much quieter and use much less power and are much cheaper. Building an 8-Bit Adder still requires 144 transistors (more if you replace the ripple carry with a look-ahead carry), but the circuit is microscopic.

Building an 8-Bit Adder still requires 144 transistors (more if you replace the ripple carry with a look-ahead carry), but the circuit is microscopic. Chapter 13. But What About Subtraction? After you’ve convinced yourself that relays can indeed be wired together to add binary numbers, you might ask, “But what about subtraction?” Rest assured that you’re not making a nuisance of yourself by asking questions like this; you’re actually being quite perceptive. Addition and subtraction complement each other in some ways, but the mechanics of the two operations are different. An addition marches consistently from the rightmost column of digits to the leftmost column. Each carry from one column is added to the next column. We don’t carry in subtraction, however; we borrow, and that involves an intrinsically different mechanism—a messy back-and-forth kind of thing. For example, let’s look at a typical borrow-laden subtraction

When the iPhone app is built, the Xamarin C# compiler generates C# Intermediate Language (IL) as usual, but it then makes use of the Apple compiler on the Mac to generate native iPhone machine code just like the Objective-C compiler. The calls from the app to the iPhone APIs are the same as though the application were written in Objective-C. For the Android app, the Xamarin C# compiler generates IL, which runs on a version of Mono on the device alongside the Java engine, but the API calls from the app are pretty

We could just as reasonably base our number system on eight (if we were cartoon characters) or four (if we were lobsters) or even two (if we were dolphins).

In 1948, while working for Bell Telephone Laboratories, he published a paper in the Bell System Technical Journal entitled "A Mathematical Theory of Communication" that not only introduced the word bit in print but established a field of study today known as information theory. Information theory is concerned with transmitting digital information in the presence of noise (which usually prevents all the information from getting through) and how to compensate for that. In 1949, he wrote the first article about programming a computer to play chess, and in 1952 he designed a mechanical mouse controlled by relays that could learn its way around a maze. Shannon was also well known at Bell Labs for riding a unicycle and juggling simultaneously.

Code: The Hidden Language of Computer Hardware and Software Quotes

Code is not like other how-computers-work books. It doesn't have big color illustrations of disk drives with arrows showing how the data sweeps into the computer. Code has no drawings of trains carrying a cargo of zeros and ones. Metaphors and similes are wonderful literary devices but they do nothing but obscure the beauty of technology.
