Master computer networking from fundamentals to advanced production systems with this practical, comprehensive guide.
Computer Networks: From Fundamentals to Advanced Systems takes readers from the foundations of network communication to modern enterprise, cloud, security, and distributed networking architectures. The book focuses not only on definitions, but also on how protocols work, how traffic moves through a network, how systems fail, and how engineers troubleshoot and design reliable networks.
Inside, you will explore:
Networking fundamentals and communication models
OSI and TCP/IP architectures
Physical and Data Link Layer concepts
Ethernet, switching, VLANs and STP
IPv4, IPv6, CIDR and subnetting
ARP, ICMP, DHCP and network configuration
Routing fundamentals and routing protocols
TCP, UDP and transport-layer behavior
DNS, HTTP, HTTPS and TLS
Wireless and mobile networking
Network security, VPNs and Zero Trust
Network troubleshooting and performance engineering
Cloud, virtual and container networking
Distributed systems and advanced networking
Network architecture, reliability and system design
Each unit combines conceptual explanations with real-world scenarios, troubleshooting approaches, hands-on laboratory exercises, interview questions, review questions, and architecture-oriented design exercises.
Whether you are a computer science student, networking learner, software engineer, cloud engineer, DevOps professional, cybersecurity learner, or aspiring network engineer, this book provides a structured path from networking fundamentals to modern production-oriented systems.
