The state of two or more events or processes happening at the same time. / The agreement or coincidence of opinions or actions.
[C/U] Both
pl: concurrencies
In technical environments, particularly computing, this term describes the ability of a system to handle multiple tasks overlapping in time. It does not necessarily mean they are executing at the exact same microsecond, but rather that they are in progress simultaneously without one blocking the other.
In legal or formal contexts, it refers to the overlapping of time periods, such as when two prison sentences are served concurrently rather than consecutively. It carries a sense of alignment and synchronization, whether in timing, logic, or agreement.
Uncountable when referring to the general concept of simultaneous existence. Countable when referring to specific instances of overlapping events or technical concurrency levels.
