In the second module, we continue to explore the OSI/ISO Model. In specific, we learn about the Data Link, the Network, and the Transport Layers. We then learn about Local Area Networks along with the Wireshark Protocol Analyzer. During this module, we learned more about layer two and layer three functions. Specific learning topics include relevant TCP/IP family protocols such as ARP, UDP, TCP, DHCP and DNS. Network layer functions including routing and addressing are also covered. We also learned about the hardware that operates at these levels such as switches and routers.
I personally thought this module was the most difficult module since I was bit lost with our assignments. This module made me realize the importance of the textbook. A lot of my classmates and I have forgotten that this class was a hybrid and that it really needs our individual efforts to do our own study time outside of the classroom. In this module, we focused more into the SOHO routers, and specifically looked in the DATA link layer. Since we learned about the TCP/IP layers, we focused in the protocols such as the ARP, UDP, and etc. Professor Crowley also used the Wireshark to demonstrate as well. My favorite assignment for this Module goes to TCP/IP and Subnet Masking because it taught me more specifics of the TCP/IP models.
