Between this last week and this week it's the final push for the intro to computer networks course. The final this last weekend and this week is the wrapping up of our last group project and classwork on firewalls. This past week covered the link layer, both in physical hardware and software. I enjoyed exploring more about the slotted ALOHA protocol. We covered how ARP allows us to translate IP addresses to MAC addresses, allowing IP-layer communication to occur over the link layer. This class was a fun exploration into a much deeper networking world than I had once been aware of, and truly makes you appreciate all the smaller systems that work hand in hand to bring us the internet (and other computer networks) as we know them today.
