Morphology

UNIX + operating + system

The phrase is fully compositional: 'UNIX' names a specific operating system and 'operating system' transparently denotes software that manages hardware and runs programs. This modifier–noun structure is standard and cross-linguistically common, so a B1 learner who knows the constituent words would readily infer the meaning.

Etymology

UNIX operating system comes from a joke about an older, complex system called 'Multics'. The makers called their much smaller system Unics as a joke, later spelled UNIX, and that short name stuck, so today UNIX operating system refers to a family of stable systems used on many computers, for example to run websites.
