Computer Networks

I believe the first running of the class was in late 2012, so the content is still quite current. The course lasts 12 weeks and walks you through a wide range of major topics related computer networks work from the physical layer of sending signals on wires or through the air to network security and quality of service. The class provides insight into how many things you likely use every day actually work, like Ethernet, Wifi, routers, switches, hubs, virtual private networks, content distribution network, peer to peer services, and of course, the domain name system and the Internet itself.

The lectures go into a fair bit of technical detail about how different aspects of computer networks function. In some cases, the extra detail is enlightening it can get a bit tedious. Overall, the class was definitely worth taking, even though it does not require any programming. I'd recommend this course to anyone that wants to learn how computers networks work in more depth than you'd gain in your everyday life as a web user.
