I Thought I Understood Computers… Until I Opened One

I used to understand computers in theory until I started working on them.

Through hands-on practice, I assembled PCs, configured BIOS settings, installed Windows and Linux (including dual boot), set up LAN networks, and troubleshot printers.

Opening a system unit changed my perspective. Computers aren't just devices they're interconnected systems where power, airflow, configuration, and precision all matter.

Networking taught me that one wrong IP address can stop communication. Printer troubleshooting showed me how hardware, drivers, and networks interact in complex ways.

But the biggest lesson wasn't technical.

It was learning structured troubleshooting diagnosing step by step instead of guessing.

That shift from theory to practice made all the difference.

Because in IT, understanding is good but hands-on experience builds real competence.
