Thoughts on reading "The World is Digital" (complementary)

"The World is digital" is the world's top computer scientist Brian W. Kernighan to the general reader of the introductory book, for a computer has been learning for n years of professionals, this book may be a little easier, but I still seriously over, found that there is a certain receipt, Because it is difficult for a person to master all the knowledge in this field, there will be some deficiencies, there are always some things you do not know, or have not understood but it is necessary to know the knowledge, I read this book in the process of this feeling, often there is a sense of the epiphany. At the beginning of the book, the author says. Indeed, in this computer age, everyone is connected to computers, and computers have penetrated every corner of the world. Therefore, it is necessary to learn some necessary computer knowledge.

What does a computer consist of? What is the CPU? What do you mean by software? What do you mean system? What about programming? What are the Internet, the World Wide Web, data, information, and computing? From hardware to software to communication, it is step by step, the author methodically introduced to us all aspects of knowledge, that is, these things 1.1 points of the world connected together. The global village is a global village, I think a large part of it is because of computers and networks. The computer's function seems to have changed from the beginning to the present-computing and related work. However, its internal structure and its materials are changing at an alarming rate. Getting faster and more portable ... These are the manifestations of changes in physical properties. Wireless network This magical thing, we often use WiFi, the use of high school physics often contact with the electromagnetic waves to transmit signals. The receiver receives a signal with a strength proportional to the transmitter's power, inversely proportional to the distance to the transmitter, which is what we normally use when the router is out of its signal coverage and cannot be used.

In this digital world, not everyone has to learn to hit the code, write the program, these are the programmers, but understand the basics of computer knowledge and how it works is what everyone should do, the president or civilians are the same.
