Computer Networking

About this Course

This is an advanced Computer Networking course that delves into the latest concepts and tools used by the CN industry.

[

Want to build on your Computer Networking knowledge or move into Network Engineering positions such as Systems Admin, Network Admin or Technical Operations (WebOps)? If so, this is the class for you.

Computer Networking takes a hands-on approach to teaching very technical material, using Mininet (a network emulator) to show you how a computer network functions, what factors contribute to its efficiency and how to overcome inherent limitations.
