The Book of the World is digital

Thoughts on reading "The World is digital"

Once again in the teacher's recommendation, with the last read "I am a IT small Bird" exploration and surprise, I looked at the watercress on the second computer book "The World Is digital" and the last reading, it is A popular science reader written by the world's top computer scientists.

The author has personally experienced the various stages of computer development, and then use the easy-to-understand strokes to show us the digital technology development trajectory and the impact of these technologies on daily life. Yes, the world today is digital, our lives are moving towards digital development, and constantly upgrading

It is suitable for computer beginners and non-computer professionals to read. I am a freshman, the contents of the book is simple and clear, so I read a lot of questions and feelings, such as what drives the development of the computer it will go in the direction of development. Of course, I have to read it later before I know. This book is a comprehensive interpretation of today's computer and communication convenient working methods and hardware software, the Internet and so on.  Also introduced became the software virus how the Internet was formed and in what way connected. This book tells us that no matter how changeable today's technology, people are unchanged. Let us learn more about the computer, by reading this book to let us know that we are not enough, let us more perfect ourselves, learn more new knowledge with the development of science and technology, computers, communications systems, and the digital products supported by them are everywhere!

One of my most serious reading of the algorithm is the most interesting to let me know that all of the compression algorithm is to reduce or eliminate the use of the string, the main methods include the high frequency of the elements encoded into a short string, the construction of a frequency dictionary, using numbers instead of repeating content. Digital TV's tearing into blocks or sound is intermittent, indicating that the decompression algorithm encountered an input error, it may be that the data arrives fast enough. There is a limit to any compression.

In general, this book is not just a general introduction to the computer, it is divided into three parts in detail: software, hardware, and communication. What is software? In fact, we often download under the mobile phone some QQ AH. In fact, no matter what we use, behind the operation of the code, so we all understand how the programmer to everyone's daily important role. As a member of the learning software, after reading this book not only did not have the first in front of this professional confusion still want to inspire themselves to explore the hidden mysteries of the computer. In fact, we live in the touch of the computer, mobile phones, tablets are hardware, with the development of science and technology, the shape of the hardware more and more convenient to carry, to facilitate our travel. Speaking of communication, in this digital era to solve the world side of the family's missing to solve some of the company's meeting trouble because of the communication can be opened video conferencing. These advantages are undeniable.

It is very useful for us to learn software engineering, whether you are a computer student or a programming enthusiast, it will benefit you a lot. Let the future in the study of computers everywhere more clear goals.
