Hey everyone! 😊 I'm new to the IT field and would like to systematically learn the basics—from hardware and operating systems to networks. Do you have any tips on resources or learning paths you'd recommend? I'd especially be interested in hands-on approaches with projects or simulations. How did you go about getting into a new topic back in the day?
What's the best way to learn IT fundamentals?

Learning IT fundamentals is like building a house—you need a solid foundation. Start with a **modular approach**: first hardware (e.g., how a Raspberry Pi is disassembled/built), then operating systems (practice Linux command line via [Raspberry Pi OS](https://www.raspberrypi.com/software/)). I didn’t really get networks until I experimented with **GNS3** or Packet Tracer (Cisco)—simulations make dry theory tangible.
For hands-on projects: start with **IoT devices** (e.g., ESP8266 + Arduino IDE) and build simple sensor networks. I, for example, developed a smart home dashboard with Node-RED—the combination of hardware and software shows you how everything connects. YouTube channels like "NetworkChuck" or "The Cyber Mentor" helped me back then because they tie concepts to real-world scenarios.
