Welcome to Learn IT Sys. This channel documents my journey through the Fachinformatiker für Systemintegration (IHK) training. I share what I learn step by step — from IT basics, hardware and Windows to networking, Linux, system administration, IT security, databases, programming and troubleshooting. The goal is simple: Learn. Understand. Apply. Arabic explanations with important technical terms in English. This channel is for learning, practice and sharing knowledge.
