  • A very useful side effect of our model is that a thread's synchronization-free regions appear indivisible or atomic.

And so now our abstractions are like atomic units when we're actually talking about thought here or truth.

Examples

  • Atomic operations on the file system provide synchronization of processes against the file system.

Morphology

atomic = atom (semi-transparent) = atom + ic

The computing sense ('indivisible') is a metaphorical shift from the physical notion of an atom as indivisible; learners who only know the physical/chemical sense may not infer this technical usage.

Etymology

The word atomic comes from Greek atomos 'not cut', because a- means 'not' and tomos means 'cut'. That's why in computing an atomic operation is one that cannot be 'cut' into parts but either happens completely or not at all.
