Web Seminar Essay

Carlos Dominguez is a Senior Vice President at Cisco. He is also a motivational speaker who show his audiences on how technology is changing the world in terms of how we communicate, and more importantly how we work. From listening to his Web Seminar i personally feel more motivated in learning more about technology and pursuing a career in the fields of technology. He explained very thoroughly, even to the extent where he put it into three main ideas. I also was able to see how quickly the world is changing in terms of technology. Giving me a detailed explanation of how advanced we are becoming to the point where we just keep growing and advancing farther.

According to Carlos Dominguez the way in which you become a change agent is by embracing the changes that occur in your life. I think what he means by that is to learn and adapt to what is happening around you. Technology is changing rapidly and we should adapt to that idea. The more that we know about the changes that are happening around us the better understanding we get of what is happening around us. Having the right technology accompanied with the right culture you get a winning company. It doesn't pay off just to have good technology to be successful. If you lack the motivation and dedication then the technology is practically useless. How do you think all this great technology was able to advance so far in only a few decades. It is because people came out with new ideas with the technology they already had, and made it better. Examples of this are everywhere. Originally the first of computers were huge and took so much time just to process simple messages. As time passed people made it smaller, faster, and efficient. This better technology made communication so much better, and the spreading of ideas so much easier.That is what is meant by technology and the right culture making winning companies.

The Web Seminar had three main ideas that it was trying to teach us. One is how quickly things are changing. Social networks such as facebook have skyrocketed in terms of users. In 7 years it went from 0 to 750 million users. That shows how many people are know almost interconnected with each other. Not just facebook but even twitter. These sites are the reason some dictators in the middle east have fallen. People would get together through facebook and spread the word. This has been very common these past years. the second idea is power of the people. As groups we have shown that we can do anything. As i stated before the overthrowing of dictators in the middle east is evidence of that power. The information we put on the internet is for us to control and manipulate. Third idea is that everything is going to be connected. Meaning that everything around us including where we live, refrigerators, desks, kitchen counters, etc. A really awesome commercial was shown where an example of how everything would look like if it where interconnected. There screens everywhere from the kitchen counter, mirror in the bathroom etc. the person was literally texting to someone on the mirror of the bathroom which is incredible. The idea of a house of the future being like that really motivated me to dedicate myself to make a difference in the field of technology.

What impacted me the most about this Web Seminar was the idea of how everything will soon be interconnected. That part of the Seminar is what really impacted me to dedicate myself to learning all i can about technology. I really want to be apart of that future idea and build into it if i can. I think that i could possibly follow into Carlos's footsteps in terms of making technology impact our lives much more then it already has. To the point where we literally can't live without technology. i believe that technology is priceless in terms of how much it benefits us in communication, work load, etc. Technology really impacts our lives greatly since we use almost all the time.

To summarize this the three main points given to me by this seminar have really opened my eyes on how beneficial and attached technology is in our lives. i knew before hand the importance of technology but this has shown much more. The idea of how quick things are changing, power of the people, and everything being interconnected, has really motivated me to continue learning about networking. Carlos Rodriguez is someone i would like to follow, in terms of his ideas, and hi views toward technology. Hopefully this motivation has spread to other people since more people would be more beneficial to succeed in the future. Just like Carlos's

main idea of power of the people. In groups we can do everything.

Chapter 8 Case Study

What's the name of this kind of interference?

The name of this interference is called external interference.

Explain why it can slow down the network traffic?

It can slow down the network traffic because the cables is where all data are being sent through. With the extra cables added behind the walls the signaling interferes with the cables of the ACME server and switch. This interference or "noise" is the source of the external interference.

Would the result of the tests be any different if the networking cabling was running next to a just installed small alarm clock instead of an A/C unit? Why?

I think that installing a small alarm clock would most likely result in better results because compared to the A/C unit it takes more power and wiring. The alarm clock has its benefits over the A/C, like less interference since and as a result better flow in the network.

Lab 5.6.1 Reflection

For Lab 5.6.1 by reading the information on the lab i was able to learn that the config isn't the only way of solving IP routing problems. You can also use the Cisco Internetwork Operating system command line interface to solve problems on the local area network(which will be showed in later packet tracer labs). I also learned that the inspecting tool can be used to examine the routing table in packet tracer. I was also able to learn how to configure a route using a GUI(Graphic User Interface). I would have to configure the router with address and subnet mask as 0.0.0.0, and also the next hop as 10.10.6. This configuration  would make any packet that came from the LAN would be directed towards the R1-ISP Router. The most important thing that i learned from this lab which was a on going problem through the other labs was the reason why a added PDU would always fail the first time to the extent where you would have to press the "fire" button to resend it. The problem was that the ARP table were not yet populated.

Reflection questions:
The data that a IP packet can contain is things from the destination IP address, source address, Protocols etc.
What is meant by the phrase the "IP packet has been routed" means that it has traveled through the network and reached the destination. A route is a pathway in which packets travel through. These routes can be configured based on the best possible way to send the packets to the user's wishes. The places where things go wrong could be from the routes to even the devices. If devices or routes aren't configured correctly than packets would either never be sent or on the most likely be lost or dropped.

Lab 4.6.1 Reflection

This lab I wasn't able to get up to but by reading all the tasks i understood what information i would have gotten out of it. This lab has the same addressing table as the previous labs before. So in terms of ip address, interface, subnet mask, and gateway all the configurations have remained the same. the only thing that did change was the server. There is a new IP address, and default gateway. Just like the previous lab task 1's main focus is on repairing and testing the topology. It tells me that adding a simple PDU would appear in the PDU list window as part of  "scenario 0". By than pressing  the "Fire" button in the PDU list window would send the test ping a second time to the point where it will this time be successful. One thing that i learned from this lab is that by event  filter being set to display DNS, UDP, HTTP, TCP, and IMCP and than opening a web browser from the desktop of computer 1A and finally typing the URL eagle-server.example.com in combination with the use of capture/foward button will show me the interaction between the DNS, UDP, HTTP, and TCP.

Reflection Question: comparing and contrasting DNS, HTTP, UDP, TCP
DNS: Domain Name System which is a naming system for computers, services etc.
HTTP: Hyper Text Transfer Protocol which is a networking protocol for web pages.
UDP: User Datagram Protocol is a transport layer protocol that runs on top of ip networks.
TCP: Transmission Control  Protocol similar like the UDP which is one of the main protocols used for the internet protocol suite(Also a transport layer protocol).

Lab 3.5.1 Reflection

In lab 3.5.1 i was able to easily set up the topology given since the addressing table's have been the same for three consecutive labs so far. For task 1 i was able to configure the necessary devices with IP, subnet mask. default gateway, etc. I connected eagle server to the  R1-ISP from the Fa0/0 port .I added a simple PDU but just like the previous lab the packet had problems going to the routers. It eventually went to the eagle server but failed there as well. Based on the lab what should of happened was that the simple PDU should of appeared in the PDU list window as part of "Scenario 0".  I understand that the first time i were to send the the one shot ping message that it would fail because of the ARP(Address Resolution Protocol). By clicking on the fire button(which is in the PDU list window) will send the packet a second time which will be successful .  Base on the question on the reflection what happens when you type a Url into a browser and a webpage comes back is that the client requests information from the server in whcih the server accepts and sends information back in the form of a webpage based on the requested URL .The type of client/server interaction that is present is that the client Pc-PT 1b is requesting information from the Server in which the server will accept the the request and act accordingly.

Lab 2.7.1 Reflection

In this this lab we used packet tracer to set up another network. The topology diagram showed us a basic set up of how it is suppose to turn out.  I was able the set up the network and configure all the devices correctly as the lab suggested me to. But for some reason there was still problems with the pack simulation. As the packets traveled to the other devices once it got to the router it would show an "X" on the packet meaning most likely that there was a problem with the packet being sent to the router. This occurred when i added the simple PDU as a test message from computer 1b to the eagle server. It failed to even go past the router for some unknown reason. What would happen if it was successful the packet would have appeared in the event list as a packet that was "detected" or "sniffed". Task 3 told me to switch to simulation mode in  which i would able to examine the packet in each step as it went through each device. In task 4 it told me to experiment a little with topology given. I was able to progress more than the previous set up and as a result was able to get a better understanding of what this lab wanted to teach me.

1.) The way in which the video relates to me and the class is that it has to do with computing. TO be more specific programming. I found the video to be very interesting since the kid was so young and yet was still able to come up with an idea and follow through with it.

2.) This is a good reflection of self discipline because the kid in the video is so young but is smart and disciplined enough to go through with making an app. Many teenagers can learn from this adolescent because not many teens and kids are as disciplined as him to be this professional and such a young age. It also takes commitment and dedication and goes for show that anything is possible.

3.) I personally think that both this subject and creating an app are difficult in their own way. Like the kid said in the video creating a program could be hard. The reason why is because you have limited resources. You can't really ask your parents because the odds of them knowing is very slim. You can always go on the internet, but you could be either charged, but if you find the information needed you wouldn't really have someone to ask for help with if you got a problem with how you're writing your program. Cisco is also difficult because you don't just have to know things through software but also on a hardware level. Especially when  your troubleshooting problems in a network. You would have to go up the layers troubleshooting to see in which layer the problem originated from, and when finally finding it fixing it. I think that Cisco is most likely a little harder than creating an app. With an app you are writing endless lines of code. You can most likely fix something easily if you make a mistake in making a app. But for Cisco for troubleshooting you need to look through on a software and hardware level in order to mediate a problem.
