Management Information System in Computer Science

The textbook takes a layered approach to teaching computer networking, starting with the application layer and working its way down to the physical layer. The book covers a range of topics, including network protocols, network architecture, application layer protocols such as HTTP, transport layer protocols such as TCP and UDP, network layer protocols such as IP, link layer protocols such as Ethernet, wireless and mobile networks, network security, and network management. One of the key features of the book is its focus on the top-down approach to teaching computer networking, which means that it emphasizes the big picture and the overall design of networks before delving into the technical details. This approach is designed to help students understand how the different layers of a network work together to provide end-to-end communication.
