Class Overview

We use computer networks every day; check emails, browse social network sites, watch videos on smartphones, etc. This course provides fundamental knowledge and principles of how computer networks work. We cover the full networking stack, starting from the applications, including the web and HTTP. We then study the transport protocols, in particular, TCP, and routing algorithms and protocols for the Internet. We investigate how the link layer protocols such as the Ethernet and Wi-Fi handle multiple access. By taking this course, you should be able to answer the questions such as “how does addressing work in the Internet?”, “why is Wi-Fi sometimes slower than LTE?”, “how is my video chat with a friend across the world be in such high quality?”, “how can all IoT devices be connected to the Internet?”, “what network vulnerabilities do hackers exploit?”. The course includes lab sessions that provide you hands-on learning experience of TCP and networking. The course also showcases recent research highlights in networking by showing a few short videos.
