The Book of the World is digital

In today's society, computers, communication systems, and digital products supported by them have penetrated our lives, and this book is designed to let us understand this world of numbers. The author, with simple and clear language and easy to understand examples, led me to visit a computer-owned world, so that I might understand the digital world of my own life.

The book from the hardware to explain, and then to the software, finally to the communication, the book is very comfortable reading, not so much a textbook, rather than a story book, its examples are very easy to understand or interesting, read very convenient, because immediately can think of this is probably what it looks like. In the second chapter introduced the binary system in a sentence very interesting, that is, "there are only ten kinds of people in the world , understand the binary and do not understand the binary system." "After reading this sentence, I should never forget what the binary system is." It lets me know how important a good algorithm is to a program. It solves my confusion about how Wi-Fi really does it, and let me know what a tall Wi- fi "IEEE 802.11b/g/n ". This book has refreshed my knowledge of computers and broadened my horizons for the digital world. It summed up a very comprehensive, filled a lot of my knowledge of the computer gap, can be considered as I read a real computer primer book.

This book let me know a lot, also let me know I need to know more, we live in a changing era, especially for computers, from1981Year first generationPCthe processor frequency is4.77MHzto the author when he wrote this book.2.3GHz, almost. -times, and now the Universal8Gmemory is about the first generation.64Kof the -million times! As the book says, some of what he wrote at the time might seem out of date today. However, no matter how changeable today's technology, people are unchanged. I should seriously learn the current professional courses, like in the building of high-rise buildings will lay a good foundation, I am now learning like a foundation, only the foundation to play well will not be in the future to learn new knowledge, not as now learning so embarrassed (becauseCLanguage Foundation is not solid, now the data structure is very tired of learning. But think I just keep on learning every day, the foundation of a solid, and then personally compiled the program is not yet, that sense of accomplishment is certainly very good. Look forward to my future growth, haha.

Finally thank the author for writing this book, but also thank the teacher let me know the book.
