This week was the last week did not feature any new materials and we instead resubmitted some previous programming assignments and prepared for the final. Overall, I really enjoyed this class and learned a great deal about operating systems and how they manage programs, memory and data transfer. This class had given me a greater appreciation for the critical function that the operating system provides. One aspect that sticks out in my mind is the concept of the kernel. I know in previously I had heard the term, but never really knew what it was. I now understand what the kernel is and how it works, so now when I see a vague error about the kernel in my operating system I have some idea what it is talking about. Beyond that the other concepts explored in this class have helped me to become a more well rounded computer science major.
This week, we developed a deeper understanding of the network control plane and explored routing algorithms such as Dijkstra and Bellman-Ford, focusing on how they determine the most efficient paths for data transfer. We also learned about the SDN control plane, which allows for dynamic network management and routing. In addition to the theory learned this week, we conducted a network lab exploring the use of a basic SDN controller using Mininet and Wireshark. We looked at how Internet Control Message Protocol (ICMP), can be used for network diagnostics, particularly for network troubleshooting with tools like ping and traceroute.
