"The World is a digital book"

"The World is Digital", by Brian W. Kernighan, a professor at Princeton University, comprehensively introduces the internal structure of the computer and how it operates, including the basic unit bits (bite) of the computer, the understanding of CPUs, software systems, communication methods, and the World Wide Web. is a beginner, introductory book, for the first year of our help is very big, let us realize that we are living in a world of data. Echo 10 years ago, the internet has just entered China, 3g network has not covered the country, the data of the world is not very deep, can be 10 years later today, under the guidance of this book, I realized that they have been surrounded by data. At home, with TV, computer, in school to buckle mobile phones, everything is tied to the data tightly.

This book is divided into three parts, hardware, software and communication. This book is to let us know the first computer's production time, and the first "engineer" was actually the inventor of the loom. Today, the digital universal, the development of digitalization let us realize that we should grasp the tail of the data, we must accept it and use it well.

In terms of hardware, we need to know clearly the composition of the computer, to know how the data is represented and how it is handled, and in terms of software, it is important to know how to describe the questions raised by the questioner and to lay a good foundation for the data algorithm. Remember in the programmer Developer Roadmap: The language you learn will be your tool for learning the next language, and the first language is a large part of the language that determines the quality of the latter. This emphasizes the importance of learning the first language and playing a good foundation. This book rarely involves how to learn, more is introduced, not the heart chicken soup model, but brick by brick introduction. Communication, big to the Internet, small to the microphone, is a way of information transmission.

In addition, the book has a bright front of the book and the vocabulary behind it, it introduces a lot of nouns in detail.

　　Not long ago, I thought that learning software does not have to learn these, whenever someone asked me xx computer parts bad to do, whenever I met about the computer operation mode of the topic, I always vague, to "I am learning software, but not learning hardware," the words vague past, But in the future today will be confused by these things, only understand the simple, basic code, but do not know what they are running the computer inside is what kind of operation, combination way;

A true pursuit of knowledge should be widely understood, not for learning and learning. To enrich themselves as the motive force, and constantly enrich themselves, continue to learn more and more deeply in the professional.
