Usage tips
Word composition
'Betriebssystem' (operating system) is a compound noun made up of 'der Betrieb' (operation/function) and 'das System' (system). The linking -s- connects the two parts. Literally, it is therefore a 'system for the operation' of a computer.
EXAMPLE
Ohne ein Betriebssystem kann der Computer nicht starten.
Without an operating system, the computer cannot start.
Typical verbs
In connection with an operating system, the verbs 'installieren' (to install), 'aktualisieren' (to update), 'starten' (to start), or 'hochfahren' (to boot up) are often used. You also say that a program 'läuft auf' or 'läuft unter' einem Betriebssystem (runs on/under an operating system).
EXAMPLE
Ich muss mein Betriebssystem dringend aktualisieren.
I urgently need to update my operating system.
Register and style
In technical conversations or in colloquial language, the English abbreviation 'OS' (for Operating System) is often used. However, 'Betriebssystem' (operating system) is the correct and generally understood German term.
EXAMPLE
Welches Betriebssystem nutzt du auf deinem Rechner?
Which operating system do you use on your computer?

Betriebssystem vs Programm
program
'das Programm' and 'das Betriebssystem' both belong to computer language. A 'Programm' is an application that you use to do a specific task, for example writing, calculating, or editing pictures. The 'Betriebssystem' is the basic software on a computer or phone. It makes sure that the devices work and that programs can run. The words can be confused because both are software. Put simply: the operating system is the foundation; programs are what you use on it.
Betriebssystem
Auf dem alten Laptop ist ein neues Betriebssystem installiert.
A new operating system is installed on the old laptop.
Programm
Für den Deutschkurs öffnet Maria ein Programm zum Schreiben.
For the German course, Maria opens a program for writing.
