This week I gained a better understanding of how packets are moved across the network and appear on each devices network adapter. The most interesting part for me was watching our Roku's keep sending ARP requests on the network. It's nice to know that regardless of changes to the network our Roku's will work hard to find their way to the internet and the netflix servers. The videos, reading, and exercises also helped to detach network protocols from networking hardware for me. Around my desk I've got all different kinds of radios and networking devices that use wires, 915mhz, and 2.4ghz for Zigbee, Lora, Wifi, CAN, etc so it is important for me to understand the different layers involved in networks.
As someone who took half this class before my expectations were pretty clear for content coverage. This does seem like an area you can play around with for a while and keep learning new things so I was not disappointed by watching the same videos and absorbing new information from them. There were unexpected aspects regarding the format for homework submission but I liked those changes. Having everything use the quiz submission form seems like a good way to keep things organized within the CMS instead of having us upload files with all questions answered.
