Week 4 Posting - RAID

I learned this week about RAID, which stands for Redundant Array of Independent Disks. Before this, I thought data storage simply meant having a hard drive, but RAID has entirely changed how I think about what is considered reliable and quality storage. 

RAID combines multiple drives into one functional working drive. Depending on the RAID level, it can either make a computer run faster or protect it from data loss. Some RAID levels can do both. RAID 0 focuses on splitting data, RAID 1 mirrors a copy, and RAID 5 and RAID 6 balance performance and fault tolerance using parity blocks to rebuild data. The most advanced RAID is level 10 and offers high speed and high protection through combining striping and mirroring. I have now realized that RAID is meant for all types of users, not just professionals, to help get the most out of our computers and prevent data loss.

Week 5 Posting - Windows Media Creation Tool

I recently built a computer and failed to realize that using a Windows 10 installation drive I had purchased years ago was not the best idea. It caused a lot of issues because the old version of Windows did not have any drivers for my modern hardware. My computer would turn on but not allow display when plugged into the GPU, which made it difficult to complete the setup. Since I had integrated graphics with my CPU, I attempted to just update Windows, but since it was so outdated, it struggled to download and properly install each update. This is when I learned about the Windows Media Creation Tool and how important it can be when working with computers running the Windows operating system. Using the tools allows you to create a Windows OS installation drive that can be used offline with the most recent version of Windows and its latest drivers. Using this instead of the drive you can purchase from a store such as Best Buy or Micro Center allows you to ensure compatibility when working ...

Week 8 Posting - Backdoors

I recently watched a meeting between the Chinese president, Xi Jinping, and the South Korean president, Lee Jae-myung, where the Chinese president gifted two new Xiaomi smartphones to the South Korean president. The two exchanged jokes about the device's security, and the Chinese president even joked about checking for backdoors. Backdoors are not necessarily a new topic for me, but they did, however, pique my interest in the history of backdoors. Backdoors deliberately undermine the users' security by allowing for a direct access point to the device; however, these can be implemented for many reasons. Knowing these Xiaomi phones are banned in America, it made me curious how many backdoors have been created in modern technology for government surveillance. It has brought me back to the idea of how every sheet of paper printed can be traced back to a specific printer based on a unique ID printed on each sheet of paper. It is small steps like these that allow for a higher level o...

Week 3 Posting - Memory

This week I really deepened my understanding of how memory works in a computer but, more importantly, learned how the brand choice plays a crucial (no pun intended) role depending on what type of system you are trying to build. For desktop builds we lean towards memory that offers the users maximum power because we are typically trying to get the most out of our system when we use it. As someone who plays a lot of video games, it is very important to have high speeds with a large amount of memory to ensure smooth speeds. Utilizing an AMD CPU allows me to have smoother gameplay experiences because my CPU is memory dependent and scales based on the total amount of memory the system has. I recently upgraded my build and improved my speeds slightly, making my next upgrade a GPU. I can understand now why memory built for servers is built for longevity and stability. They are not necessarily looking for the fastest speeds but the most stable and reliable speed to ensure maximum lifespan.
