Post #4 Travelling Through a Network

 I pinged Google, a website from Japan, and a website from Germany. Both the websites from Japan and Germany averaged at 21ms, while Google averaged at 23ms. I am not sure how this happened. Logically, it should taken longer for the pings to go to the domains that are farther away than Google, yet somehow they were both 2ms faster on average. Other times where I have used ping and traceroute, the geographical location and distance directly and proportionately affected the speed of the pings and traceroutes. The more distance they had to go, the longer average time it took. The results I have gotten here are very peculiar to me and I will have to look more into why Google was the slowest. Ping and traceroute can be used to troubleshoot servers or websites if you cannot reach what you are trying to reach. Using the ping command will simply let you know whether or not a host is reachable or to give you latency times about that host. You can use traceroute if you need a more detailed answer as to where the packets are getting stuck or how many "hops" are needed to get from you to the destination. For example, let's say to get to Google, it is four hops, but it is not working. You can ping Google to see if Google is reachable. If so, then you can use traceroute to make sure the packets are successfully hitting all the hops. If the packets get stuck on one of the hops, then you have located the problem on what is stopping you from reaching Google. This can be used if you work in IT and have access to each of those hops' locations to fix the issue. Two reasons for an error or timeout response would be either the host being unreachable (down), or if the network has a lot of traffic and not enough bandwidth to carry the packets.

Post #7 E-commerce Sites

Introduction              Many people use e-commerce websites frequently , without knowing how they truly work. But before we can dive into how e-commerce sites work, we first need to learn what they are. E -commerce, standing for electronic commerce, is the process of customers shopping online and processing their payment. (Hirz, 2025). Essentially, e-commerce is just online shopping, and an e-commerce site is how shoppers buy goods online. A well known example of an e-commerce site is Amazon.com. People search for what they want to buy, add it to their virtual cart , pay using a payment method, and then the site will deliver the item to the customer in a set amount of days. What many people do not know is just how these e-commerce sites work and how much programming goes into building a f unctioning e-commerce site. From front end development, back end development, database management, and all the programming that connects them all tog...

Post #1 Programming Languages

Scratch Project   I have some previous experience using Scratch from a programming course I took in high school, roughly 4 years ago. Some insights that I gained after completing my Scratch project were grasping the fundamentals of how a computer requires the information to function the way I want it to. If  I was not precise enough with my instructions, then the program would do something I did not intend it to do. This showed me that when coding, I have to know what I am planning to do beforehand, and code exactly that in order for it to work properly The differences I noticed between Scratch and other written programming languages are plenty. In Scratch, the blocks are pre-coded, so it is a drag-and-drop system to get the program to do what you want. But with other languages, you have to type everything out. The programming language I found to be easiest to understand, aside from Scratch, is Python. I found the syntax that Python uses to be simple and easier to understand ...
