Post #4 – Traveling Through a Network



What a Struggle....

This was actually my least favorite part of the course. I was completely lost and confused. I had never heard of the terms "Ping Command" or " Traceroute". I really didn't score well on this assignment, but I was able to complete the assignment partially. 

This week, I learned how data travels across the internet using two important tools: ping and traceroute. These commands introduced me to understanding how packets move from my computer to websites around the world.


While using the Ping Command, I performed test on the following websites:

  • Google.com (Packets: Sent = 4, Received, =4 Lost = 0, Maximum = 149ms)
  • BPN.com    ( Packets: Sent =4, Received = 4, Lost = 0, Maximum = 51ms)
  • Baidu.com   ( Packets: Sent =4, Received = 4, Lost = 0, Maximum = 291)








I also had to use the command Traceroute for the very first time to see the path that the packets take to reach each of the following websites.

  • Google.com: (20 hops, smooth route, final latency ~21 ms) 
  • Baidu.com: (23 hops, Consistent RTT= 231 )
  • Nic.br:      ((Brazil) – Reached at hop 4, latency between 202–283 ms )













This week, I learned how data travels across the internet using two tools called ping and traceroute. These commands helped me see how packets move from my computer to websites around the world, and how long it takes for them to get there and back.

Using the ping command, I learned how to test several websites. Google.com responded quickly with an average roundtrip time of 12 milliseconds. BPN.com was slightly slower at 22 milliseconds, and Baidu.com which is located in China had a much higher latency of 266 milliseconds. That showed me how distance affects speed.

Next, I used the traceroute command to see the path my packets took. Google.com had a smooth route with 20 hops and low latency. BPN.com followed a similar path. Baidu.com took a longer route across the Pacific Ocean, which explained the higher latency.


I even traced routes to Brazil (nic.br) and Asia (www.whsifen.com), and both showed higher roundtrip times well over 200 milliseconds because of the long distance and international routing.

From these tests, I learned that roundtrip time increases with geographical distance. Servers that are closer respond faster. Servers that are overseas take longer because the data has to travel through more routers and across oceans.

Ping and traceroute are great tools for troubleshooting internet problems. Ping tells you if a server is reachable and how stable the connection is. Traceroute shows me where delays or failures happen along the way. Sometimes these tools don’t work sometimes because a firewall blocks them or because the network is too congested to respond.

Overall, this assignment helped me understand how the internet really works. It’s not just clicking a link but it’s a journey of packets across routers, networks, and continents. Now I know a little bit more about how to test and troubleshoot connections like a tech pro.

Post #2 – My Review of the Samsung Health App

Image
  The Ole Reliable Samsung Health App... For Week 2 of this course, we were given an assignment to discuss a familiar web or mobile application. I chose to review one of my favorite mobile applications which is the Samsung Health mobile application. I have used this app for years to track my fitness goals, sleep patterns, and overall wellness. As someone who values physical health and is learning more about technology, I found this assignment both useful and personal. Usability Samsung Health is one of my favorite applications because it is very easy to use. The home screen allows me to view my daily steps, my heart rate, sleep patterns, and other key health stats. I can also swipe through different sections and customize what I specifically want to track to track. The app also allows me to connect with my smartwatch and other devices, which makes tracking automatic and convenient. Design The design is super clean and simple. It uses calming colors and clear icons works for me. Eac...

From Pest to Protect: About Me

Image
My Journey from Exterminator to Cyber Defender.... 🧠 Introduction For over two decades, I built my life around solving problems—first with my hands, then with me  business. From crawling under homes to eliminate infestations to mentoring others in pest control, I’ve  always believed in protecting what matters. Now, I’m taking that same mindset into the digital world,  where the threats are invisible but just as real. 🔄 Why the Shift? After years of running a successful pest control company, I felt a pull toward something deeper. I  wanted to protect not just homes, but data, identities, and communities. Cybersecurity isn’t just about  firewalls and passwords—it’s about defending people. That mission aligns perfectly with who I’ve  always been. 🎓 Back to School After 20 Years Enrolling in college again after two decades wasn’t easy. I had doubts. But I also had driven. I’m now  studying Cyber and Data Security Technology at UAGC, learning everything...

Post #1- " A Programmer in the Making"

Image
  My First Programming Experience with Scratch This week, I created my very first program using Scratch, a beginner programming platform developed by the world-renowned MIT. At first, I was completely clueless on what to do. I’ve built a career working in pest control for years, and now I’m diving into tech!! What was I thinking!!The Scratch platform actually helped me to understand a little bit better and made it easier than I thought. I was able to build a simple animation where my character (called a sprite) moved across the screen, changed costumes, and responded to user input. I actually creating a soccer themed animation!! The drag-and-drop blocks helped me understand basic programming concepts like motion, loops, and events. I was able to learn that the order of blocks matters even if they’re out of place, the program won’t work right. I had to test and fix things until everything ran smoothly. That process of trial and error taught me a lot about problem-solving. One of the...
