Chapter 1 of the American Computer Science Master's course "Computer Networking: A Top-Down Approach" introduces students to the fundamental concepts of computer networking. The chapter aims to provide a "big picture" view of the Internet and the terminology associated with it, laying the groundwork for more in-depth exploration in later modules.
The PowerPoint slides for this chapter are freely available to faculty, students, and readers, allowing for modification and customization to fit individual needs. The authors, Jim Kurose and Keith Ross, have put in a lot of effort to create these materials and only ask for proper attribution in return.
The chapter begins by defining the Internet and explaining the concept of protocols. It then delves into the components of a network, including the network edge (hosts, access networks, and physical media) and the network core (packet and circuit switching, Internet structure). Performance metrics such as loss, delay, and throughput are discussed, as well as security considerations in computer networks.
Overall, Chapter 1 provides an introduction to the key concepts and components of computer networking, setting the stage for deeper exploration in subsequent chapters. Students are encouraged to use the Internet as a real-world example to better understand the complex interactions and technologies that make up modern network communications.
