Traveling Through a Network Reflection Essay

So for this week's discussion, we will be breaking down how ping tests and trace routes work. The two are somewhat similar but have their differences. The ping test lets you send data via packets to the address that you have selected, and it sends back the allotted time that it took to get there. We use this at my job quite often, considering I work for a large ISP, and we get called out for trouble calls about packet loss. We use the command -t to send a continuous ping so it can gather a larger pool of data. It's quite simple if you are sending 100 and get back 90, you have a 10% packet loss. Trace Routes are a little different than ping tests. A traceroute gives you the path that your packet is traveling. When you have this data, you can see where there is any drop-off and where it was when this happened. This is crucial for troubleshooting internet issues because sometimes someone's problem may not be directly at the location. For example, if you look at the traceroute to australia.gov.au you can see we start to see no response after it leaves Comcast's backbone. They each take a different path to their end destination, but they all leave from the same spot, which travels through your ISP's head end and backbone. As far as when they make a return with no response, the Ping test will do that if the packet was unable to be delivered and there was no response. As mentioned above, this is known as packet loss. During a traceroute, just like the ping test, if no response is given, it will result in no information. This is also known as packet loss. It will skip over and go to the next hop.

Applying Algorithmic Design and Data Structure Techniques

 Java Newbie? Come on In! Today we will be talking about applying algorithmic design and data structure techniques in developing structured programs. Do not fret; I intend to take you through this as a newbie to a newbie would! First, we need to understand what algorithmic design and data structure techniques are. A data structure is a particular way of storing and organizing data so that it can be used efficiently. Arrays, trees, linked lists, stacks, graphs, etc. are all data structures that allow us to perform different operations on data. Algorithm design is simply just a collection of different steps that will lead you to the correct output. The two work hand in hand by influencing each other more specifically the design of the end result.  Are some algorithms and data structure designs better than others? In my opinion yes they absolutely can be. It is highly definitive on the desired output that you are seeking. Both of these complement each other to prod...

Summary Blog Post     Understanding the fundamental concepts underlying operating systems provides a solid foundation for comprehending the features, structures, and mechanisms employed by contemporary operating systems. This knowledge is valuable for a range of roles involving system administration, software development, and working with computer systems in various domains.     While being in this course, I have gained new insights into how operating systems theory works as well as understanding the fundamental concepts that underlie operating systems. When these concepts combine, they form the foundation for the design and functionality of contemporary operating systems. Below are my responses for the final questions for this course. I will say that this course was a vast venture into how the theory and design of operating systems truly work and function.  Describe Features of Contemporary Operating Systems and Their Structures     St...

Documenting a Day

     Thanks to this assignment, I could really dig into these applications and try them out in detail. I was able to see which I would prefer to work with versus one that I may choose not to. In this essay, I will compare the functions of Word processors, Spreadsheet, Presentation, and database applications and the disadvantages and advantages of each application.             The functions of each of these applications vary from application to application. Word has a ton of options at your fingertips as far as how you want something to be typed and processed. It also gives you the assistance with the editor and word count functions. Excel, to me, is a data processing application that you can input statistics and have them formulated for you automatically, pending the formula you use. This is great for business applications and anywhere you may need to produce numbers. PowerPoint is an excellent tool for office use as its primary purpose ...
