Objectives: Our goals in our third lab were to learn about the OSI Model in order to better understand modern computer networks.
Equipment List: A computer with internet access.
Notes and Observations: Our first task was to open the command prompt. Once in the program, we entered “ipconfig / all” to display the IP and MAC addresses for our computer. We were then to attempt to ping our neighbors computer, which was connected to ours via network cable. We did this by typing the command “ping” followed by their IP address. This only worked when the Firewall was deactivated. After that, our next task was to connect computers to a switch. On our computer, we created a new connection, which included naming the connection, connecting using “com 3”, and setting the bits to “9600 bits per second” and flow control to “none”. From there, we opened the mac address table and were able to tell the mac addresses of the two computers apart. The final task was using the “tracert” command to show the path and “distance” that it takes to get to a specified website, such as “ksu.edu” or “google.com”. We also chose to try a site of our choice. Mine was “titanmotorsports.com” which turned out to be the highest “virtual distance” among our tested websites. I believe it hit 17 points between it’s Orlando location, and our computer.

Conclusions: We learned about the first 3 layers of the OSI model by experience, which works well for me. I learn best by doing things. I don’t yet fully understand the OSI model, but this lab helped push me along a bit further with my knowledge.
