Traveling Through a Network


In the ping activity, I pinged three different websites. Other than the ping rate which is in milliseconds, I pretty much got the same result 4 packets sent with no loss. Based on my own professional experience, if you do have a packet loss, it’s usually a network impairment somewhere. Sometimes this could be on your ISP side, or it could be on your side like your network card or software on your computer. The traceroute command had more detailed information showing how many routers were passed through and how long it took to get from router to router. The routers that I’m referring to are the Internet Backbone “A complex network of fiber-optic cables, routers, switches, and other networking hardware makes up the internet backbone, which enables data transmission between various internet service providers (Lynch, 2023). Between the three websites I did a traceroute on, the milliseconds varied from router to router. From what I’ve learned over the years is that between 50ms and 120ms is good. Once you start to get around 150ms or higher you may have latency in your network. Ping and traceroute command can assist you with troubleshooting latency and internet connectivity issues.

I worked as a customer representative for DSL broadband, and I did a lot of troubleshooting using ping and traceroute. Most of the time, if the customer could not access the internet, we would try to ping their ISP provided router. If pinging the router was successful, and you still could not access the internet there was more than likely a firewall blocking the connection. I also had to troubleshoot customers issue who could not access a particular website. I would have the customer do a traceroute on their computer to see were we had a request time out. Most of the time, we could not fix that problem because when you send a packet you cannot determine how it’s going to get to that location. In that situation, we would send out another router in case the website blocked MAC address for the router.

Ping and Traceroute command are good troubleshooting tools. A couple issues that are talked about is latency and ping rate. From my experiences, the further a server the higher the ping rate. This explains why my ping rate to the .jp website may be a little higher than someone who actually lives in that geographical location. Depending on your location, your ping rate may be higher pinging google.com.au website versus google.com. With that said, ping and traceroute are good tools and are very necessary for troubleshooting connectivity issues. One thing to remember to is that you have limited control on how your packet gets to and from a destination.

Programming Languages

During week 1 of the Information Technoloy course, we discussed programming languages. There are many different languages that are use to make programs. We focused on Scratch which is a user friendly program which makes programming fun for kids or adults. In an interactive activity in our textbook I was able to use Python in which I thought was for advanced progammers. Python was a little more difficult to use than Scracth. With Python you have to know how to make your own algorithms to make some programs work. And I believe that's what made it harder beacuse you have to know what code to use. On the other hand, Scratch was a very good program to use for novice users because most of the code is precoded. There are code blocks that you can use to make simple programs. I believe it is a good way to give someone an understanding of what can be done with programming. I had the pleasure of using Scratch and making a program. If you would like to check it out the link is below. In m...

Documenting a Day

In Week 2 of my Information Technology course, I created a journal where I created an entry on how Microsoft Word is used daily.Most of my encounters with Microsoft Word are at work and at home doing my school work.Most of Microsoft Windows’s software that is used for writing and presentation have some of the same functionality. The ribbon bar on the top of each program is identical on each application. Microsoft word, Excel and Power Point all have a home, insert, design, and draw selections and they all include word formatting option. It may have been done purposely because it makes it easier for the user when switching between each software program. School Assignments Writing Most of my school assignments are written in word processor in an essay form. I’ am given a directive from our instructor about how the essay needs to be formatted. Most academic papers for writing assignments are done in APA format. There must be a title and reference page. Font and size must be done acc...

Network Security

There are many people that use the internet daily, according to PEW 85% of Americans say they use the internet daily, including 31% who say they use it almost constantly, 48% who say they use it several times a day, and 6% who say they use it once or twice a day (Pew Research Center, 2021). Most of us may use the internet for web browsing or for checking email. There are several important things an internet user should know when browsing around. And there are many problems an internet user can run into while browsing.The internet is full of safe things to do, but you must be aware of everything you do. Internet safety should be a big concern for internet users. There are serveral network security vulnerabilities that a user could encounter while using the internet.These vulnertabilities could include a Ping, DDos, Phishing attack, or Email spam. Phishing attacks are carried out through email or text messages and can be very damaging to an internet user. Phishing emails and text mes...
