Which concept allows multiple events to be handled concurrently in sensor systems?

The concept that allows multiple events to be handled concurrently in sensor systems is concurrency. Concurrency refers to the ability of a system to manage multiple tasks or processes simultaneously. In the context of sensor systems, which often collect and process data in real-time, concurrency is crucial because it enables the system to respond to multiple sensor inputs and events at once without delay. This approach enhances the system's efficiency and responsiveness, allowing it to manage various operations like data collection, processing, and communication with other components effectively.

While multitasking and asynchronous processing are related concepts, concurrency specifically encompasses the simultaneous management of event handling, making it the most appropriate answer in this context. Multitasking typically refers to a broader capability of running multiple tasks, whereas asynchronous processing involves operations that allow tasks to initiate and complete independently of one another, often using callbacks or event loops to manage the flow of execution. In contrast, concurrency is the overarching principle that enables these functions to be performed simultaneously within a system, particularly in environments such as sensor networks, where timely processing of events is critical.
