Daily Term: Atomic Operation

Atomic Operation

An Atomic Operation is an operation that completes in a single, uninterruptible step, ensuring consistency in concurrent environments. For example, in Java, the AtomicInteger class provides methods like incrementAndGet() that atomically increment a value, avoiding race conditions without explicit locks. Atomic operations are efficient for simple tasks, like counters, but they’re limited in scope and can’t handle complex multi-step operations.
