This course will provide students with an overview of networking concepts and technologies. It is meant as a primer for non-majors, i.e., for students who don’t have networking as a core course in their curriculum. After this primer, students may choose to take other networking courses for delving deeper into specific technologies.

Intended audience: Computer networking
