Lab Exercise 3 (OSI Model)

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 “” or “”. We also chose to try a site of our choice. Mine was “” 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.

Questions: None

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.


Optional Cable Making Lab Exercise (Lab 2)

Objectives: The objectives for this lab were to create a straight-through cable, which is used to connect a computers NIC to a Hub. We were also to create a crossover cable which allows two different computers to share files while connected. 

Equipment: Crimp tool, wire cutter, 3-feet of CAT5 UTP, 2 RJ-45 connectors, and a simple network system or tester.

Notes and Observations: My partner and I gathered the necessary tools and supplies. We then used a wire cutter to remove the RJ-45 connector from the end of the CAT5 cable. Immediately after, we stripped the insulation to partially expose some of the wiring. We then straightened the wires out and organized them as follows: (Left>Right) Orange Stripe, Orange, Green Stripe, Blue, Blue Stripe, Green, Brown Stripe, Brown. After performing this on both ends of the cable, we tested our connection. It worked, so we moved onto the next portion of the lab assignment.

We then did a crossover connection, which follows the same process for assembly, but the arrangement of the internal wires are different. They are as follows: (Left>Right) Green Stripe, Green, Orange Stripe, Blue, Blue Stripe, Orange, Brown Stripe, Brown. We performed this once again on both ends and we tested our connection, which worked.

Questions: No questions.

Conclusions: Nicholas and I created a crossover connection, and a straight-through connection, both working successfully.

Networking Lab 1

Objectives: The objectives for our first lab were:

1. Create a blog.

2. Join/ Edit the Networking Class Wiki.

3. Create a Diigo account and join the KSU Networking Diigo Group, then share a webpage on that group.

4. Write a lab report and post it here.

Equipment List: A computer with internet connection 

Notes and Observations: I had already created a blog (this) and a Diigo account for my previous Digital Media courses, so that part was already taken care of. I then joined our Networking Wiki and made sure I was able to post into it. I posted a Networking related article into our Diigo group, and that finished the lab.

Questions: None

Conclusions: I accessed my Diigo, blog, and networking wiki accounts and double checked to be sure I could post in each.
