1 <strong>Abk</strong>ürzungen<br />

Gehen wir von 30 Zeichen aus, aus denen <strong>Abk</strong>ürzungen gebildet werden, und nehmen wir<br />

eine größte Länge von 5 Zeichen an, so lassen sich 25.137.930 verschiedene <strong>Abk</strong>ürzungen bilden<br />

(Kombinationen mit Wiederholung und Berücksichtigung der Reihenfolge). Es folgt eine<br />

Auswahl von rund 13000 <strong>Abk</strong>ürzungen aus den Bereichen Informatik und Telekommunikation.<br />

Die <strong>Abk</strong>ürzungen werden hier durchgehend groß geschrieben, Akzente, Bindestriche und<br />

dergleichen wurden weggelassen. Einige <strong>Abk</strong>ürzungen sind geschützte Namen; diese sind<br />

nicht gekennzeichnet. Die Liste beschreibt nur den Gebrauch, sie legt nicht eine Definition<br />

fest.<br />
