atomicitet

Atomicitet is a concept describing the property of something to function as an indivisible unit in a given context. The term is used across disciplines to emphasize unbroken execution or unit integrity.

In computer science, atomicitet refers to the all-or-nothing nature of a transaction or operation. It ensures that a set of changes is applied completely or not at all. Implementations include database transactions, file systems, and concurrency control, typically enforced through locking, logging, or compensation mechanisms.

In physics and chemistry, atomicitet relates to atoms as the fundamental building blocks of matter. Historically atoms were regarded as indivisible particles; modern science recognizes subatomic structure, but the term persists in common language and certain theoretical contexts as the idea of an indivisible unit.

Etymology and usage: The term stems from Greek roots; in Scandinavian languages it translates to “atomicitet” for “atomicity.” It is used in technical writing to discuss qualitative aspects of systems that should behave as a single unit.

In computing, challenges arise when attempting atomicitet across distributed systems. Partial failures and network partitions make true atomicity difficult to guarantee, often leading to trade-offs with eventual consistency or recovery mechanisms such as the two-phase commit protocol.
