Network Protocols and Architectures
Mock Exam
Course Introduction
This course provides a comprehensive exploration of the foundational principles and practical implementation of modern network protocols and architectures. Students will examine layered network models, such as OSI and TCP/IP, and study the mechanisms underlying data transmission, addressing, routing, and congestion control. The course covers widely used protocols including Ethernet, IP, TCP, UDP, HTTP, and emerging topics like wireless, mobile, and software-defined networks. Through lectures and hands-on projects, students develop an understanding of protocol design, performance metrics, security issues, and the evolving landscape of computer networking.
