Tech Topic Connection: Scratch Programming & The IT

Foundations Behind It When I first built my Convertible Cruise Simulator using Scratch, I thought I was just playing with visual blocks and animations. However, after digging into the fundamentals of information technology throughout this course, I’ve come to realize that this beginner-friendly tool actually represents the core of computer science in action. From hardware and software to databases and network security, Scratch touches more foundational IT concepts than you might expect. Computer Science & How Computers Operate Scratch may be simple, but it introduces key ideas like loops, conditionals, variables, and event-driven programming—concepts at the heart of all modern software. Underneath the colorful interface, it mimics how real computers operate: processing instructions, storing values in memory, and responding to user input. It’s a visual way to understand how computers execute code in a sequence and how logic and structure affect behavior. Hardware Dependence Even ...

Network Security: Shielding Our Digital World

 In today’s hyper-connected world, information and system security isn’t optional—it’s survival. Whether you’re running a business or just managing your personal devices, protecting your digital assets is critical. With cyber threats constantly evolving, understanding how attacks work—and how to defend against them—is essential for everyone. 🧭 Why System Security Matters For individuals, system security keeps private data, like bank info, passwords, and personal messages, out of the wrong hands. For businesses, it protects everything from customer records to internal communications. One security breach can lead to financial losses, legal issues, and a permanently damaged reputation. Security isn’t just about avoiding problems; it’s about staying resilient, prepared, and a step ahead of attackers. 🛠️ When a Ping Becomes a Weapon Most people use the ping command to test if a website or server is online. But attackers can weaponize this simple tool: Ping Flood : Overwhelms a server ...

Computers in the Workplace: Sales, AI, and the Road Ahead

 In the modern sales industry, computers are no longer just helpful—they’re mission-critical. Whether you’re managing inventory, generating performance reports, or handling customer accounts, digital tools are the backbone of sales operations. In my own experience working in retail and telecom, I’ve seen firsthand how much we rely on computers to streamline transactions, solve customer problems, and track key metrics in real time. 💡 Why Computer Literacy Matters in Sales Being computer literate is more than knowing how to send an email—it’s about understanding how to efficiently use systems like CRMs (Customer Relationship Management platforms), point-of-sale interfaces, cloud-based tools, and data tracking software. In the sales world, speed and precision matter. If you’re fumbling with the software, you’re slowing down sales, frustrating customers, and potentially missing targets. Computer literacy also empowers employees to: Analyze customer trends through dashboards and report...

Traveling Through a Network: Tracing the Digital Highway

  This week, I dove deep into how data actually travels across the internet. Using basic network tools— ping and traceroute —I ran diagnostics on three global websites: Google , ABC Australia , and ECNS China . What I found was a behind-the-scenes look at how location, content delivery networks (CDNs), and internet infrastructure shape your browsing experience. 🚀 Ping Results: Speed Check from My Terminal I ran four ping attempts for each site: WebsiteAvg. Latency Packet Loss Google.com 25 ms 0% ABC.net.au 18 ms 0% ECNS.cn 48 ms 0% 🔎 What stood out? Even though ABC is an Australian site, it had the lowest latency. This was likely due to Akamai’s CDN hosting content closer to me in the U.S., proving that server proximity isn’t always what it seems. 🛰️ Traceroute Results: Mapping the Journey Using Tracert in PowerShell, I saw how many “hops” data takes to reach each site: WebsiteTotal HopsNotes Google.com 27 Timed out on final hops—normal for Google due to ICMP filtering. ABC.ne...

Documenting a Day With Microsoft Office: A Real-World Application Test Drive

 For this project, I documented a typical day using four different types of application software: a word processor, a spreadsheet, a presentation tool, and a database. Each platform offered a unique way to process, analyze, and present the same information. What stood out the most? How each tool has its strengths, limitations, and ideal use cases depending on the job at hand. 📝 Word Processor – Microsoft Word I started by writing a personal journal entry using Microsoft Word. It was intuitive and efficient. Word allowed me to format the entry clearly with bullet points, headings, and alignment. It’s perfect for communication-based tasks like essays, cover letters, or daily logs. However, it’s not ideal for visualizing or analyzing data. If I needed to calculate time spent on tasks or track trends, Word fell short. 📊 Spreadsheet – Microsoft Excel This was the most powerful tool in the mix. I used Excel to break down how I spent my time, calculate percentages, and create a pie...
