Abkürzungen

Gehen wir von 30 Zeichen aus, aus denen Abkürzungen gebildet werden, und nehmenwir eine größte Länge von 5 Zeichen an, so lassen sich 25.137.930 verschiedene Abkür-zungen bilden (Kombinationen mit Wiederholung und Berücksichtigung der Reihenfolge).Es folgt eine Auswahl von rund 15000 Abkürzungen aus den Bereichen Informatik undTelekommunikation. Die Abkürzungen werden hier durchgehend groß geschrieben, Akzen-te, Bindestriche und dergleichen wurden weggelassen. Einige Abkürzungen sind geschützteNamen; diese sind nicht gekennzeichnet. Die Liste beschreibt nur den Gebrauch, sie legtnicht eine Definition fest.
