Ram and PSU presentations: BOOM! POW! K-RAM! (and PSU) - Kien

 RAM Presentations: 


You’ve probably heard of RAM before from someone tech-savvy or complaining about their computer's slowness. But what is RAM? Well, essentially we learned that it’s the computer’s short-term storage or memory. It stores data quickly and allows the computer to load applications without buffering on a loading screen for hours. Let's say you opened a window and googled “Cute cat photos” then you opened another window and googled “Cute dog photos” Ram is the reason why you’re able to open both windows without closing one. Googling “Cute cat photos” stored the prompt as data in the memory, this means you can re-open the window without the computer needing to reload it. 

We learned that there are three types of RAM: SRAM, DRAM, and Flash-Ram. SRAM is directly connected to the CPU, it is fast and compact, but, the price range for it is very high. DRAM on the other hand is larger and slower than SRAM however this makes it a lot cheaper and easier to get. Both SRAM and DRAM are volatile, meaning it requires constant power to keep data. Finally, there’s Flash-Ram which is a Non-Volatile form of storage, because of this it is used for long-term storage. You might know this one from USB drives and unlike the other types, it is mounted directly onto the motherboard. There are countless options for whatever computer build you’re looking for between all three of these.




 









Power supply Presentations:


Something we needed to remember when building our PCs is the power supply (duh, I mean computers need A LOT of power to function). These are important because you can't just plug your computer directly into the wall, as the actual PC parts need a different type of power than the one found in your outlet. To cope with this the power supply uses three conversions to turn your outlet power into power for your PC. The regular electrical waves from the outlet are fed into the transformer which lowers the voltage, they are then led to the rectifier which smooths out the waves and makes them move in one direction, your electrical waves are now ready for powering your PC! There are two types of power supply, Non-Modular, and Modular, Non-modular has a fixed amount of cables while Modular has custom amounts.

Day 4 - An amazing trip to Micro Center! - Brandon

Image
    The day started with double-checking our builds for compatibility and stock before going to Micro Center. With an early lunch and a game of Uno, we were ready to depart to Micro Center to purchase our parts. While in Mirco Center we went to the back to find all our planned parts. We didn't run into any problems at Micro Center. We had three employees help us find everything that we needed. We anticipated that we would run into problems at Micro Center so we budgeted the whole afternoon for the trip. We didn't need the whole afternoon to find everything, so we decided to walk over to Chick-fil-A. After eating a second lunch, it was time to get all the parts back to school. Today was an exhilarating day and we all really enjoyed it. We are all very excited to get back on Tuesday to build!

Compute a Computer - Final Day (Ashley)

Image
  Today was the final day of Compute A Computer. It was a victory lap for the most part, but not without a few hiccups early on in the day. We began by installing an operating system on everyone’s computer. Some people chose Linux, but the vast majority of us are using Windows 11, because it’s more user accessible and Aiden was able to transfer it to our new computers easily. We also began downloading various apps on our computers, to test their capabilities and design activities for the rest of the day.  We played some Minecraft, some Red Dead Redemption, and finished the day with a competitive game of skribbl.io.  We also finished up our J-Term presentation, which we’ll be presenting next Friday. Overall, I would say the class has been a resounding success! I’ve really enjoyed seeing everyone’s computers come to life and it’s been extremely rewarding to see a class I created be so successful and fun for everyone involved.   I encountered a couple hiccups along the way, including havi

Day 1 - First Day On the Job! - Gustavo Alvarez

Image
  Our day began with our student teacher, Aiden Cunningham, leading the class with an introduction into our computer course. In the morning we learned about the different computer parts that go into "computing a computer" and how each piece operates. Later, we went into groups of 2 and began making presentations to learn more about the specifics of these computer parts. My partner and I studied the inner workings of the motherboard, while other pairs did the same with different parts that we were introduced to in the morning. The positive vibes in our group have us excited for more learning in the upcoming sessions. The parts we researched on were; the CPU, GPU, RAM, storage (SSD's and HDD's), and the different ways to cool the CPU (Fans & water cooling). Making presentations together made learning fun!     (Presentations that were made) Overall this day was fun and productive, and our group and I are excited for the rest to come! We're ready for more compute
