Computer Networks / Fall 2025
Course Description
This course offers an in-depth exploration of computer networks, adopting a top-down approach to present the fundamental concepts and principles. Beginning with application-layer protocols, such as HTTP, FTP, and DNS, the course progressively delves into transport, network, and link-layer mechanisms, including TCP/IP, routing algorithms, and data link technologies. Through this approach, students will gain a holistic understanding of how the Internet functions, from high-level applications to low-level data transmission.
Topics covered include network architecture, packet-switching and circuit-switching, congestion control, software-defined networks, and wireless networks. The course also emphasizes practical applications of networking concepts through hands-on lab work and problem-solving exercises.
By the end of the course, students will have a comprehensive understanding of both theoretical and practical aspects of modern computer networks, preparing them for advanced study or careers in network administration, cybersecurity, and cloud computing.
