📚 Computer Networks (2025–2026 Edition)

📘 Computer Networks (2025–2026 Edition) is a comprehensive syllabus-based textbook designed for BSCS, BSSE, BSIT students, and networking professionals who want to master the principles, architectures, and protocols of modern computer networks. This edition includes MCQs, quizzes, and real-world case studies, providing both academic depth and practical exposure for learners and instructors alike.

The book bridges theoretical foundations with hands-on practice, covering everything from data transmission and switching to network security and emerging technologies such as SDN, IoT, and 5G. Students will learn how data travels through networks, how communication protocols operate at various layers, and how to design, configure, and secure real-world network environments.
