Kapitel 1<br />

Abkürzungen<br />

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

wir eine größte Länge von 5 Zeichen an, so lassen sich 25.137.930 verschiedene Abkürzungen<br />

bilden (Kombinationen mit Wiederholung und Berücksichtigung der Reihenfolge).<br />

Es folgt eine Auswahl von rund 15000 Abkürzungen aus den Bereichen Informatik und<br />

Telekommunikation. Die Abkürzungen werden hier durchgehend groß geschrieben, Akzente,<br />

Bindestriche und dergleichen wurden weggelassen. Einige Abkürzungen sind geschützte<br />

Namen; diese sind nicht gekennzeichnet. Die <strong>Liste</strong> beschreibt nur den Gebrauch, sie legt<br />

nicht eine Definition fest.<br />
