Tech Topic: Connection

  •  History of Computers
    In this course, TEC 101, students learned how computers function from where they started and where they are now. The advancements in technology are incredible, from the technology evolving from vacuum tubes, to switches, to the processor and RAM they use now. The first computers used vacuum tubes, as explained in the article Geeks for Geeks. Vacuum tubes control the flow of electrical current within a sealed glass enclosure where most of the air has been removed. (Geeks for Geeks, 2025)
  • Hardware of the modern Computer
    Computer hardware has evolved from the old vacuum tubes. In the modern age, computers use CPUs, RAM, Hard drives, and different devices that add to the computer, like keyboards and mouse. 

  1. CPU (brain of a computer)
  2. RAM ( Temporary memory)
  3. Hard Drives (Storage)
  4. Input/output devices (Keyboards and Mouse) 

  • Programming Language
    TEC 101 also allowed us to practice some form of programming language. We had an activity where we programmed on Scratch. This was an enjoyable exercise for me; it showed me that small commands can create actions in the programming world. It was a small understanding of a programming language. According to Geeks for Geeks, a programming language is a set of instructions and syntax used to create software programs. (Geeks for Geeks, 2025)  

  1. Python
  2. Java
  3. C
  4. C++
  5. Ruby
  • Application Software
     Software is the counter to hardware; software is the applications, programs, and operating systems that people interact with on computers. Nowadays, most people interact with programs on various devices, from computers, cellphones, watches, and TVs. The software side of a computer is programmed by coders and used by the user population. 
  • Database 
    As users, we create tons of digital data on different devices. Most of the time, we don't take a second to think about what we put online, but as users, we must protect our data. Data can be used by different people for different reasons. Companies like Uber can get data on a person's eating habits and serve them by giving users suggestions on what to eat. 
  • Network Architecture, Management, and Security
        As a culmination of the lessons, I learned that one thing makes a computer work, but multiple functions. From the lessons I learned, it is essential to think about how a person networks their systems, manages their information, and what types of programs they use, and most importantly, think about their digital security. Digital security is critical because people must protect their own digital information. For example, a company needs high digital security to protect against threats from attackers and hackers.

Web/Mobile App Critique

Image
       The app I chose to discuss is the YouTube mobile app. I chose this app because it is one of my favorite apps and has many options and ways to use it. YouTube started as a website that allowed people to upload videos, so it was a platform where people could sort and share videos. At this point, YouTube just celebrated 20 years of the first video being uploaded, “Me at the Zoo”, where one of the original website developers shared a small video of himself at the zoo. At this point, YouTube sorts through billions of videos. YouTube as a mobile app allows users to see different videos from education, music, podcasts, fitness, vlogs, shorts, etc. The app is straightforward; you can go ahead and select any video on the screen and start watching it. As a user, you can choose or search for videos and subscribe to channels that allow you to follow different creators to get a personal curation of other videos. The number of things you can do in the app is very well laid ...

Network Security

     Security of any kind is critical for personal reasons and organizational reasons. If a person does not lock their doors at home when they leave for the day, they leave their home vulnerable. Other people who may want to cause harm or anyone looking to do anything bad can have access to that person's personal belongings. When you think of personal data, most people don’t really think about how what they do online can be taken and used against them. My guess for this reaction is that online data is not tangible; a person cannot physically hold that data, so they may think it doesn’t exist. The test explains that personal data can be described as PII (personally identifiable information). The book states that PII is any information that can be used to identify a person. (CompTIA, 2024) PII can be seen as a person's name, home address, phone number, SSN, Email, and bank account number. In the world of organizations, like regular people, they have data that can be taken a...

Traveling Through a Network

       Well, learning about the two different commands, I have learned a lot from both commands, ping and traceroute. The ping command is used to communicate with a specific website or address to see if the computer and website are communicating. The ping command in troubleshooting can be used to see if a computer and a website or address communicate. In my three trials, I got no lost packets, meaning my laptop communicates perfectly fine with all the websites. The tracerouting command is used to communicate with the same websites, but it maps out all the routers it hits before getting to the website. It's a road map of all the routers hit by the website.                The difference in geographic locations makes a difference; if I traceroute a website hosted on a local server, it would take fewer hops to get the website to respond. Like the international websites, it took more hops to get to the loc...
