binary code stored in a computer system, which is stored, passed, and processed in binary form. Only when interacting with humans, as shown on the screen or printed out, will it be translated into familiar forms.2. Programs are translated into different formats by other programsBefore we said the main function of the computer is to process information, that is, processing ... 01101100 ... this binary code. There's obviously a problem with computers as a life-without-intelligence thing, how does

Line breaks in Linux and Windows
Carriage Return and line feed generate background
The origins and differences between carriage return and line feed.Before the computer appeared, there was a kind of device called teletype model 33, which can contain 10 characters per second. But there is a problem, that is, when a line breaks a line, it takes 0.2 seconds, just two characters. If a new character is passed in the 0.2 s, the character will be lost.As a result, the developers thought of a way to sol

Ask the programmer.No famous teacher pointed to the programmer's head, and then pointed to a big stone."Please make it clear !"

separated from hardware. In essence, the two can switch between each other rather than absolutely mutually exclusive. However, to a large extent, it should be said that programs have changed the world, iPad, iPhone, and PC, router or server. After all, it's just a bunch of programs added to the "Smelly skins. There is no depression in the field of electronic engineering and related manufacturing. I just want to emphasize the soul role of software. As a programmer, I personally want to pay tribu

In the title of this article, we use the word "restoration", instead of "Resurrection", which is clearly intended, meaning that the infinitely small calculus has restored the glory of the year, I have taken back my crown ".
In the past, leveniz invented the "infinitely small" and used it for the analysis and research of the local state of the function. After the computation process was completed, the non-zero infinitely small was abandoned, making peo
for people all the way, however, it has never been our main development goal to improve the efficiency of machine work.
This is the "Paradox" that I have just mentioned that makes me confused.
Let's take a look at the development path of the programming language to learn more about this trend. First, our early programmers put a line on the tape to represent the holes in the machine code, and then handed it to the machine for processing. Then we invented
reconfigure the syntax and semantics of the XL.Procedural programming LanguagesProcedural (imperative) programming means that you need to specify the steps that the program should achieve in its intended state. A procedure is a set of statements that can be referenced by a procedure call. The process helps the code in moderation. Programming makes programs structured and easy to track program flow.

Through the wireframe, we can plan and define the logical structure behind the responsive visual effects. (For Wireframe prototypes, refer to our previous "wireframe prototype's nature and Practical Application Overview")
We have planned several typical screen sizes based on previous research and estimated results. In this case, we've chosen three typical mainstream d
Recently, foreign media sources said that Apple will host two new iphone launch next year, in the spring is a generation of the iphone 6s, and the traditional autumn is the iphone 7. While this may seem to be somewhat unacceptable, it has been explained by the foreign media.
Foreign media stableytimes reports that Apple has been doing so to shorten the iphone's release cycle, and to keep up with the more frequent launch of new machines by competitors. On the other hand, the iphone will be use
, designers still need to design the first iphone as a benchmark and then create a twice-fold image resource. Because all iphones use the same size, eventually the system's suitability makes the same content appear in exactly the same physical size as the two resolutions.

In designing a new ipad application, we still design the first
