Which process type occurs on a predetermined time and is not user-initiated?

The concept of a process that occurs on a predetermined time and is not user-initiated is best represented by the Scheduled Process. This type of process is designed to run according to a specific schedule, such as daily, weekly, or monthly, allowing for automation of tasks without requiring user intervention. Scheduled Processes are ideal for repeating tasks, such as generating reports, sending out notifications, or performing data updates at specified intervals.

In contrast, the other options involve different triggers or mechanisms: Ad-hoc Requests are typically initiated spontaneously by users as needed, Automated Processes may utilize specific triggers but do not solely rely on a set schedule, and Triggered Processes respond to events or changes within the system rather than occurring at predetermined times. Thus, the Scheduled Process stands out as the correct choice for the question, aligning perfectly with its defined characteristics of timing and automation.
