handle concurrency |support concurrency |manage concurrency |concurrency model |concurrency control |concurrency limit |high concurrency |concurrency issue |concurrency bug |database concurrency
Sinonime
overlapping execution (descriptive and close in technical meaning) | multitasking (more general; often used for users, operating systems, or work habits) | parallelism (related, but usually means actual simultaneous execution, often on multiple cores)
Antonime
sequential execution (tasks run one after another rather than overlapping) | serial execution (technical term for operations processed in a single sequence) | single-threaded execution (one thread of control, often with little or no concurrency)
Teme
software |computing |programming |systems
Definiție

the way a computer system works on several tasks at the same time or during overlapping time periods

In computing, the ability or practice of running multiple tasks, processes, threads, or requests during overlapping periods, so they can make progress independently.

Colocații
concurrency of events |concurrency of factors |concurrency of risks |temporal concurrency |apparent concurrency |degree of concurrency |concurrency between events |concurrency with another process
Sinonime
simultaneity (formal and very close in meaning) | co-occurrence (emphasizes that things occur together, often without implying a cause) | overlap (more common and practical; may refer to partial shared time)
Antonime
sequence (events happen in order rather than at the same time) | succession (one thing follows another) | separation (things are kept apart in time or occurrence)
Teme
time |analysis |formal_writing
Definiție
