The Book of the World is digital

Today's world is digital, our lives are moving towards digital development, and constantly upgrading.

    Recently, I read the book World is digital, a world-class computer scientist who was a senior researcher at the Bell Labs Computing Science Center, and is now a professor at Princeton University, Brian W. Kernighan. He is language and ampl unix Span style= "font-family: the song Body;" And many other systems, while publishing the the C programming Language the practice of programming the Elements of programming style , is even hailed as c

Open the book, see the Table of contents, is greeted by a sentence:-Any advanced technology is no different than magic.
Indeed, the world of science and technology is changing rapidly, a few years ago want to dare not think of things, now can be achieved with a variety of technologies, in order to catch up with the changes in the world, we also have to learn more technology!

The first part of the book covers some of the parts of the computer, namely "hardware", and explains the purpose of each. Computing devices have a long history, but most of the early computing devices are dedicated and are often used to predict astronomical events and their occurrence. For example, with regard to Stonehenge, an unproven speculation has been that it is an astronomical observatory. The Antiquisera machine, which was manufactured in the year BC, is an astronomical computer whose mechanical structure is stunning. These computers look different and don't feel the same, but it's just a representation, it doesn't really matter.

    The second part is software. Today's society, software and our lives are closely linked together, mobile phones, computers, electrical appliances have a variety of software. Good software can change our lives and optimize the performance of our hardware. On the contrary, a bad piece of software can make a difference! 2010 year 4 consumer Reports gx460 model "Cannot buy: There is a security risk" because its electronic stability control system will cause this SUV for our programmers, how much will be involved in software development, we should be familiar with software knowledge, so as to prevent the poor software of the above!

The final third part, is the description of "communication", thousands of years ago, people have been good at long-distance runners to send messages. 490 BC , Pheidippides from the marathon battlefield to reach Athens, the victory message to defeat the Persian people to Athens. Unfortunately, after running to Athens, he went out of breath to say "Celebrate, we win" and then die (at least that's what the legend says). It is known that communication technology is the key to the world communication, is the link of the world Unicom.

Kernighan advocates that everyone should know about computers, which, in his mind, is the equivalent of a "computer book for the future president", a must-read for a new generation of citizens. The content in this book will even affect our activities on Weibo and in the community, and the way we use smartphones. "The World is digital" is a very good book, in the hope that in the future study, but also can continue to read such a great work, so that their world view becomes wider.
