Features: To meet the development needs of the current information society and promote the rapid development of the information industry, it is essential for the general public to have basic knowledge of computer networks and the Internet, especially Internet application technologies. Therefore, most higher education institutions have designated courses related to computer networks and Internet applications as public foundational courses, while enterprises and institutions have incorporated them into public training programs. This book is designed to meet such needs.
According to teaching requirements, the content of this book is divided into two parts: Part I is on the Basics of Computer Networks, and Part II is on Internet Applications. Part I primarily covers fundamental concepts of computer networks, network architecture, network protocols, and several commonly used network protocols, as well as the basics of data communication, local area networks (LANs), and networking technologies, network interconnection. Part II introduces the basics of the Internet, the fundamental methods for accessing the Internet, and specific Internet applications—such as browsing the World Wide Web (WWW), sending and receiving email, search engines, BBS, file transfer, and network messaging.
During the writing process, emphasis was placed on moderate theoretical explanations while focusing on practical operations and applications, aiming to achieve clarity, gradual progression, and simplicity. To facilitate learning, the author consistently uses real-world examples throughout the book, which helps readers to practice and apply the knowledge by analogy, enabling them to master the basics of computer networks and Internet applications more quickly. To deepen understanding of the teaching content, consolidate learning, and improve practical skills, each chapter is accompanied by relevant exercises.
