  Final Blog Post: Exploring Network Security and IT Careers Network security is an essential element of the modern digital age, and it directly relates to nearly every fundamental idea covered in this class. From computer hardware and software knowledge to programming, databases, and network protocols, network security experts are supported by a broad foundation of information technology in defending systems and providing secure communication (Laudon & Laudon, 2021). Corresponding to IT Fundamentals Network security is closely tied to IT fundamentals such as computer systems, operating systems, and data transmission. IT professionals in this field should understand how data is transmitted, stored, and processed between systems and how weaknesses can be located and safeguarded from cyber threats. IT courses begin with these fundamentals because they form the base of any networked system, especially in cybersecurity analyst or network administrator occupations (Laudon & Laud...

    Week 1 Paper Using Scratch to develop a program was interesting to say the least. Being someone who was still learning the basics of programming, Scratch made it easier for me by allowing me to focus on logic and creativity rather than syntactic code. My project consisted of a character (sprite) traveling around the screen, changing costumes, talking at instances, and loping these actions to create a basic animation. I used event blocks to start the animation, motion blocks to get the sprite to move, and control blocks to deal with repetition. It was excellent for a drag-and-drop setup, and anticipating the result as I worked along made it a fun and engaging experience, yet frustrating at times. Insights Gained from Scratch The biggest thing I took out of this exercise is that programming is all about problem-solving and logical thinking. Scratch is not like "real" code, but it does teach fundamental programming ideas like sequencing (in which order commands are executed)...

    Hi class! Have you heard of Duolingo??? From my experience, Duolingo is a very addictive language-learning website and mobile app. It uses an exciting approach to teach vocabulary and grammar to many languages. I've had Duolingo for a while now and used it to learn. I can attest firsthand to how addictive it is and how effective it is in one being able to acquire a working proficiency in a language. Duolingo is fantastic in terms of usability. The responsive and straightforward interface makes it a pleasure to use. The lessons are bite-sized and perfect for learning on the go or in short breaks. Lessons are structured into a skill tree model, whereby each skill is taught about some specific topic like greetings, food, or family. While progressing through the lessons, you unlock new skills and visit old material. The exciting elements of the app, such as experience points (XP), streaks, and leaderboards, are highly motivating. Students earn XP for finishing courses and can ...

    Hi all, I just tried the ping and traceroute commands on some websites: google.com, yahoo.co.jp, and abc.net.au, and it gave me some fascinating insight into how information travels across the internet. The ping informs you of how long it takes a small packet of data to travel to a site and return, but traceroute (or tracert) follows the path the data takes, hop by hop, through a chain of routers along the way. Not only can you find out if a site is available,  but you can also find out how many hops you need to get to it and where any delays occur. When I attempted to access google.com, the response was fast, with an average of 19ms. It is natural, considering Google servers are typically in proximity or cached by data centers near the user. Yahoo Japan gave a much slower response time of approximately 177ms. The traceroute indicated why: the data had to take a much longer international route to reach Japan and go through numerous international network segments. What...
