Designed for students, educators, and aspiring network professionals, this book transforms complex networking concepts into a structured, intuitive learning experience. Rather than presenting protocols as isolated topics, the book follows the logical journey of a data packet as it moves through the seven layers of the OSI model. Beginning with fundamental ideas of data communication and layering, it carefully explains how information is framed, addressed, transmitted, routed, protected, and ultimately delivered. Each layer—Physical, Data Link, Network, Transport, Application, and Network Security—is explored in detail with clear explanations, real-world analogies, and practical insights. The book covers essential topics such as framing techniques, error detection and correction methods, IPv4 and IPv6 addressing, subnetting, routing algorithms, TCP and UDP communication, flow and congestion control, DNS resolution, HTTP evolution, file transfer protocols, and modern firewall architectures. Special emphasis is placed on understanding why protocols work the way they do, not just how they function. Written in a narrative and learner-friendly style, Packet Passengers bridges the gap between theoretical coursework and practical understanding. It is well-suited for undergraduate and postgraduate students of computer science and information technology, competitive exam aspirants, and anyone seeking a strong conceptual foundation in networking. With its structured approach, clarity of explanation, and comprehensive coverage, this book serves as both a classroom companion and a self-study reference for mastering the fundamentals of computer networking in today’s connected world.\u003c\/p\u003e","brand":"Ranjan Banerjee; Debmalya Mukherjee; Shankar Prasad Mitra; Malay Maity and Misha Samanta","offers":[{"title":"Default Title","offer_id":48303539749017,"sku":null,"price":449.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/4913\/0649\/files\/0f3aa9af-5226-4dc5-bc56-62e8ef484e32.png?v=1783884295","url":"https:\/\/natals.in\/products\/packet-passengers-a-journey-through-the-osi-layers","provider":"Natals Publication","version":"1.0","type":"link"}
