Features: Information itself is invisible and intangible, so to utilize it, it must be expressed in some way—this is code. The meaning of "code" is very broad; anything used to represent information can be called code. From ancient times to the present, humans have invented various kinds of "codes." In modern society, people have gradually explored a new type of "code"—digital code (Boolean algebra, binary digits). In the information age, people often input information into computers and then output processed information from computers. This book starts by discussing what information is and what it is used for, then explains that information must be coded for communication and processing. Furthermore, it must be digitized to be processed by computers, finally explaining how computers handle this digitized information. The book follows the main theme of "Information → Coding → Digitization" to describe the representation of information in computer processing. The language is easy to understand, the sentences are smooth, and it is accompanied by vivid and interesting illustrations, making it an excellent popular science book suitable for young people and computer enthusiasts.
