The Book of the World is digital

The development of human civilization has been tens of thousands of years of history, and every time the breakthrough of civilization stems from the revolution, agricultural revolution, industrial revolution. The innovations of our ancestors made us separate from other animal groups. And we are now experiencing a major revolution in human history-the digital revolution.
Today's technology products like the air in our lives, telephone, photos, music, e-mail ... The products of these technologies are developing in the direction of intellectualization, miniaturization and integration. Perhaps you have become accustomed to these high-tech, magic or habits. This is today's technology, not even advanced.
The ancients often "scholar do not go out, do know the world" to describe a person learned. And in the developed science and technology today, everyone can do this. As long as the home has a computer is at home with a knowledge of astronomy, the geography of the scholar, or even a shopping mall.
The book used the people of Tunisia and Egypt to use the Internet revolution to overthrow the dictator for many years, and the author's home for the big screen TV two things to show us the magic of the computer.
The computer began in 19th century in England, by Charles Babbage, who had spent all his life trying to build the equipment used for computing, attempting to mechanization the error-prone manual arithmetic operations, the Babbage manufacturing machine was a complex device composed of gears, wheels, levers and levers. This bulky device is the prototype of the computer now.

This book is divided into three parts hardware, software and communication

The first part of hardware, the hardware system of the computer is composed of five logic parts, such as arithmetic, controller, memory, input device and output device. CPU is the core of computer hardware system, CPU chip has hundreds of billions of transistors, with large-scale and ultra-large-scale integrated circuits. The development of integrated circuits has now had a qualitative leap. What struck me most about the hardware in the book was Gordon Moore, who mentioned in the book "More parts in integrated circuits" that the devices that could be manufactured by integrated circuits would double every two years. is called Moore's Law. Today Moore's law is still practical after 50 years. Moore's law will fail at some stage. Many people used to assert that the limits of Moore's law had arrived but later found a way to break the limits.

Part II software, what is software? Software is a collection of operations and instructions. The book is used as a recipe for food to describe this abstract computer software. The recipe lists the cooking steps and expected results of the raw materials needed to make a dish. Similar programs also describe the data to be manipulated. The development of a software requires large-scale programming, and writing code that can work together is challenging. So the birth of every good software is a great challenge to programmers.

After reading this book let me have a lot of vision for the future development of technology and technology. However, no matter how changeable today's technology, people are unchanged, no matter how the world changes, want to read this book people can use the development of science and technology to better serve mankind.
