P – Abkürzungen von Fachbegriffen aus der IT

“P” – Abkürzungsverzeichnis von Fachbegriffen aus der IT – dies bedeuten sie!

Fachsprachen gerade aus dem IT Umfeld haben es in sich! Doch gibt es für einen Fachbegriff auch noch eine Abkürzung, so haben oft selbst Experten aus einem angrenzenden Fachgebiet Probleme dessen Bedeutung zu erahnen. Aus diesem Grund haben wir hier ein kleines Abkürzungsverzeichnis aus dem EDV Bereich online gestellt.
