The Book of the World is digital

After last week's study, the teacher also recommended a book called "The World Is Digital" book, after watching I benefited. Home appliances, cars, airplanes, cameras, mobile phones, GPS navigators, and game consoles, although we can't see them, all of these devices have computing power. None of the infrastructure behind mobile communications networks, cable television networks, air traffic control systems, power systems, banking and financial services systems is supported by computers. The world today is digital, and computers and computing are everywhere. This book is about telling us everything about computers in the digital world. While the book has no enigmatic terminology, it provides a comprehensive explanation of how computing and communications work today, including hardware, software, the Internet, communications and data security, and discusses the social, political, and legal issues associated with new technologies.

The book is divided into three parts, the first part of the hardware, first explained to us what is in the computer, which includes the logical structure, physical structure and Moore's law interpretation, which makes me understand the basic structure of the computer, deepened the understanding and understanding of the computer. After introducing us to bits, bytes and information representations, this chapter gives me an idea of what I have never known before, such as the red liquid of a thermometer or the mercury column being simulated: the liquid expands or contracts proportionally with temperature changes, so that the temperature produces a smaller change, and the liquid column height correspondingly produces a smaller change. But the billboard outside the building that shows the temperature is digital: The display shows a numeric value, which is displayed as 37 when the temperature is between 36.5 and 37.4. And this part of the end to us in-depth introduction of the CPU, as the class said today's laptop, and even mobile phones have already had multiple CPUs. The Intel Core Duo processor integrates two CPUs on an integrated circuit chip. The integration of more and more processors on a chip has become a significant trend. And the book is to mention the future of CPU development and expectations, which makes me a future of computer development full of fantasy. And the second part is about the software, and this part makes my favorite part. Because I like things logically, I'm excited when I see this part of the algorithm. And then the programming and programming language and software systems have made me more in-depth on the current learning of software programming has a further understanding, improve the interest in learning programming. The third part of the communication is to describe the impact of the digital to the world, fully express the world is the number of the meaning of this topic. In this chapter I fully understand the role of the web, the Internet and the World Wide Web and the impact on our lives. After that, it was an eye-opener to the data, the information and the privacy, and a small operation on the internet could also expose a lot of personal information, which increased my attention to security issues in the future.

The small book, which contains so much content, proves the point of the book's Theme, "The World is digital". After reading this book, I am full of fantasy and anticipation for the development of today's world, hope that in the future there will be more convenient for everyone to live with things appear.
