Features: With the rapid development and widespread penetration of information technology, especially network technology, profound changes have occurred in the field of education, with revolutionary shifts in educational philosophy, models, and teaching methods. As the educational environment for cultivating 21st-century talent—schools—must stay at the forefront of societal development, it is essential to fully utilize modern information technology, particularly network technology, to build a favorable informatization environment suitable for innovative talent cultivation. To ensure the smooth operation of computer network systems in school teaching, a specialized technical personnel team is indispensable. The "Standards for Educational Technology Competencies of Primary and Secondary School Teachers (Trial)" (Technical Personnel) provides direction for technical personnel in primary and secondary schools; while the "Standards for Technical Support Personnel Competencies in Beijing Primary and Secondary Schools" sets clear and regionally aligned requirements for teachers in Beijing schools involved in information technology, thereby offering a more precise basis for training activities in basic education information technology personnel in Beijing. According to the relevant provisions of the "Standards for Technical Support Personnel Competencies in Beijing Primary and Secondary Schools," teachers involved in information technology should master the knowledge and skills related to "Internet Basics," "Data Transmission and Communication," "Network Protocols," "Basic Principles and Applications of Common Network Devices," and "Network Management." This book is compiled based on these requirements. The book consists of five chapters: Chapter 1, Internet Basics; Chapter 2, Data Transmission and Communication; Chapter 3, Network Architecture; Chapter 4, Network Devices; Chapter 5, Network Management. This book is not a professional textbook on computer network systems but rather an introduction focused on the practical network knowledge encountered in educational informatization work. It covers a broad range of network knowledge, and for in-depth study, reference to specialized books is necessary. We sincerely hope that by studying these five chapters, readers will grasp the basic knowledge of computer networks and be able to apply it as a guide when solving practical problems, cultivating their ability to address real-world challenges and achieving proficiency in their daily work.
