What does event handling refer to?

Event handling refers to the receipt of an identifiable occurrence at a designated receiver. In the context of systems like Salesforce, this means that an event is a significant change or action within the system that can trigger a response or a series of actions.

In practical terms, event handling allows different components of a software system to react dynamically to changes in state. For instance, when a user updates a record, an event is generated. This can then notify other parts of the system or external systems about this change, prompting them to take specific actions, such as updating user interfaces, sending alerts, or performing background processing.

The other choices reflect different aspects of systems operations but do not accurately define event handling. The execution of a scheduled task is more aligned with batch processing rather than reacting to real-time events. Sending notifications may occur as a consequence of event handling but is not the definition itself. Generating events without triggers does not align with the fundamental principle of what constitutes event handling, which involves identifiable occurrences that actively prompt responses.
