When it comes to the 1980’s, I am drawn to the gadgets that emerged in that decade. Much of my childhood involved the VCR, NES and an off brand of the Walkman. 1980’s technology really did become a staple in our modern lives. Though now everything has been simplified to a smart phone. Here is a good article on 80’s tech… https://www.popularmechanics.com/technology/gadgets/g1137/how-80s-technology-made-the-modern-world/

Good thing I had this already setup from last semester, but I am definitely going to put together my own website especially since I signed up for the Adobe subscription. I am also loving that this is 80’s themed! I am excited about this semester and look forward to connecting, creating, and learning.

Objective

To set up a network and then troubleshoot the problems that occurred while we were out of the room.

Equipment

routers, cables, switches, computers

Notes and Observations

We had two teams set up to complete the same task, the other team was able to get set up very quickly. My team had to do a lot of troubleshooting just to get the initial set up. One of the routers was unreachable until we used the hyper terminal. After we got it working we left the room and came back to figure out what changed to that we could fix the network. One of the issues was an extra cable, the gateway address had been changed on one of the PC’s and routing communication.

Conclusions

I think one of the reasons we had such a hard time getting set up was lack of communication and we didn’t make a diagram until after we had gotten everything connected.

Objective

To capture the frames behind the scenes and inspect them individually when looking up a webpage, pinging, a file transfer, and renew ip.

Equipment

Download Wireshark.

Notes and Observations

This was an interesting lab. It was nice to see behind the scenes and get an actual look at what is happening when you visit a webpage. It was like getting a look at the computers brain to see how it is processing the information and solving any problems it ran into like ARP.

Questions

HTTP Get: What protocol headers do you see?

-Internet Protocol-

-Transmission Control Protocol-

Conclusions

Although it did get a bit overwhelming with the mass amount of information that passes through, I was able to pick one a few things I recognized and look deeper into those.

Objective

To set up a sub network in the computer lab between 8 computers and using 4 routers and 4 switches.

Equipment

Computers, routers, switches, cables.

Notes and Observations

We had a lot of trouble getting connected within our own networks. Some of the issue was simply overlooking instructions and some were because the subnet address was not working for one of the networks. Although we have done something very similar to this before, for some reason this time we were unable to connect to the other 3 networks for most of the class period, but were finally able to get it to work after a lot of troubleshooting. One PC was not able to connect. Half way through we realized that 2 of our networks were connected to the wrong one according to the diagram(red and black were mixed up).

Conclusions

Make sure you follow the instructions closely and make sure that you are connected to the correct port. I also think if would have been helpful if we used post its with our ip addresses on the monitors and routers.

Objective

To create a web server with XAMPP and an FTP server.

Equipment

XAMPP, Brackets

Notes and Observations

We downloaded XAMPP and set up the web server. We each then created our own basic website and visited each others websites. All of this was fairly simple since I have recent experience with all of this. I have looked into downloading an FTP for my pi, but never finished it. I am very interested in this and glad I was able to get it to work to see what it was like in this lab. This was also fairly simple to do. I created a user and password and successfully was able to access the files through WinSCP, but not through Command.

Questions

What is the purpose of the loopback address? To test your web server and make sure it is working.

What does FTP stand for? File Transfer Protocol.

What is FTP used for? To remotely access files without having to be on that machine.

Conclusions

I think this is something that should be more common knowledge. Although I have some experience with this, it can still be a little confusing. I think if I watched a video of the process that I would get it better.

Objective

To create 2 networks using the lab computers and connect them with a router.

Equipment

lab computers, router, ethernet

Notes and Observations

We had to learn how to disconnect from the school network, create a new IP address and see if our computers could talk to the computers on the other network connected to the same router. We had no problem pinging the computers on our own network, but was for some reason unable to ping the other network. Turns out that if we didn’t enter the gateway address, that our 2 networks were unable to communicate with one another. We were able to quickly resolve this issue.

Conclusions

Make sure that you have the gateway address setup if you are trying to talk to a different network.

Objective

To edit the Alfred Hitchcock video to make it look like he is smiling because Forrest Gump is waving at him.

Equipment

Movie Studio Platinum, cc mixter, youtube, pwn youtube

Notes and Observations

Learned how to edit and publish a video to Youtube today. I had a lot of fun learning this valuable skill that I look forward to using often. It took me a minute to figure out the pwn youtube, but once I got it, it was very easy. Editing was surprisingly easy and user friendly for someone who is new to it. Whole project didn’t take very long at all.

Conclusions

I will definitely be using what I learned today for future projects and for fun.

Objective

To walk through the process of data encapsulation.

Equipment

“packets”,”frames”,”computers”,”printers”,”servers”,”routers”,”switches”

Notes and Observations

Each person role-played as either a switch, router, printer, server, or computer. We collaboratively put together a map of our simulated network and split it up into 3 networks connected together. We learned how to create our different addresses for our devices on our network, then sent messages across networks through the switches and routers using packets and frames. It was confusing at first, but after a little while we got the hand of it.

Conclusions

This simulation helped me to understand packets, frames, switches, routers, addressing and networking a lot better.

Objective

To learn about the OSI model in order to better understand modern computer networks.

Equipment

Hubs, Switches, Routers

Notes and Observations

Hubs and Switches are very similar in appearance and do similar tasks. Hubs send information every time to everyone and switches learn about the user and who needs what information. Routers connect at least 2 networks.

Learned how to use the command prompt to send a ping to Singapore and get my IP address.

Questions

What does the abbreviation OSI stand for? Who originated it? When?

-Open Systems Intercommunication published in 1984 and originated by ISO and CCITT.

What is the purpose of a router, switch and hub? How are the devices similar? How are they different? -Refer to Notes and Observations.

What is your IP(IPv4) address? 10.136.213.51

Conclusions

This lab helped me to understand the OSI Model better and learn what hubs, switches and routers are for and how they differentiate.
