Network Protocols and Architectures
Final Exam
Course Introduction
This course provides a comprehensive overview of network protocols and architectures that form the backbone of modern communication systems. Students will explore the functionality, design, and implementation of key protocols across various network layers, including the physical, data link, network, transport, and application layers. Emphasis is placed on protocol mechanisms such as addressing, routing, error control, flow control, and security. The course also examines architectural models such as the OSI and TCP/IP stacks, the operation of wired and wireless networks, and the interplay between protocols and emerging network technologies. Through case studies and hands-on exercises, students gain practical insights into protocol analysis, configuration, troubleshooting, and the impact of network protocols on real-world system performance and reliability.
