Week 3 Postings- reflections on chapter 3,4,5

 This week’s lessons on CPUs, RAM, and firmware really helped me understand how all the main parts of a computer work together behind the scenes. Before this, I kind of knew what a CPU and RAM were, but I didn’t fully understand how important their roles are in everyday computing.

Learning about the CPU made me realize it’s basically the “brain” of the computer, handling instructions and processing data constantly. It was interesting to see how speed and cores affect performance.

RAM was honestly a little confusing for me to fully grasp at first. I understood that it stores data temporarily, but the idea of how it constantly clears and reloads data depending on what you’re doing took some time to click. It was also a bit tricky to understand how more RAM doesn’t necessarily make a computer “faster” in every situation but instead helps with multitasking and running more programs smoothly. After going over it more, I started to see it more like short-term memory that the CPU relies on to quickly access information.

Firmware was probably the newest concept for me. I didn’t realize it acts as a bridge between hardware and software, helping everything start up and function properly. Overall, this week gave me a better appreciation for how these components work together to keep a computer running efficiently, even if some parts like RAM took a little extra effort to understand.

Week 1 Posting - Will Ai predict heart failure patients

 Through my findings of IT, I came into an article about how Ai can potentially predict which heart failure patients will worsen throughout the year. I found this very interesting because it really highlights how technology is being used in more ways than just what we have our understanding of with computers and networking. One thing that stood out to me is how the system can take something as simple as an ECG and then use it to predict future problems with the heart. Which to me sounds crazy cause normally I feel like you would expect doctors to make you take a lot of complicated tests to figure that stuff out. This could lead to less time wasted and a quicker response in the process. However, it is worth mentioning even though this technology sounds amazing it still has it challenges like dealing with messy or incomplete data. So, if the data isn't clean the predictions might not be so reliable. Which in this instance can be more detrimental since it deals more with real patients...

Week 5 Postings- Reflections

 This week’s chapter on TCP/IP and routing was honestly one of the more challenging ones, but also really important. Before this, I had heard of TCP/IP a lot, but I didn’t fully understand how it actually works behind the scenes. Learning that TCP/IP is basically the foundation of how devices communicate over a network made me realize how critical it is to everything we do online. One thing that stood out to me was how TCP and IP have different roles but work together. TCP is responsible for making sure data gets delivered correctly and in the right order, while IP handles addressing and getting the data to the right destination. I thought it was interesting how TCP breaks data into smaller packets and then reassembles them on the other end. It kind of made me think of sending a bunch of puzzle pieces that get put back together when they arrive. Routing was another part that took some time to understand. The idea that routers decide the best path for data to travel across network...

Week 7 postings- Reflections

 This week’s chapter covered troubleshooting, display technology, and virtualization, and it honestly felt like a mix of super practical stuff and more advanced concepts. The troubleshooting part stood out the most to me because it’s something I’ll actually use all the time. It’s not just about fixing things randomly, but following a step-by-step process like identifying the problem, testing solutions, and documenting what you did. I realized that being organized with troubleshooting can save a lot of time instead of just guessing and hoping something works. The section on display technology was also interesting because I never really thought about how many different types of displays there are. Learning about things like LCD, LED, and resolution differences made me realize why some screens look way better than others. It also helped me understand things like refresh rate and response time, especially for gaming or media. Now I actually get why people care so much about monitors an...
