**Ziel:** Verstehen, wie digitale Medien technisch funktionieren – von Bits bis zu globalen Distributionsnetzwerken
|
**Ziel:** Technische Grundlagen verstehen, um mit Entwicklungsteams, Kunden und Projektpartnern auf Augenhöhe zusammenarbeiten zu können.
|
||||||
|
|
||||||
|
Die Digitalisierung verändert alle Branchen. Kaum ein Projekt in der Medienwelt kommt ohne digitale Technik aus – als Produkt, Kollaborationsplattform oder Marketing-/Verkaufskanal.
