Final answer:
A background or batch process is the lowest-priority process in an operating system, intended for non-urgent tasks that don't need immediate execution, unlike real-time applications.
Step-by-step explanation:
The term you are looking for to fill in the blank is background process or batch process. In computer operating systems, processes can be prioritized based on their importance and urgency. A background or batch process is the lowest-priority process, generally intended for user applications that do not require immediate execution, as opposed to real-time applications which require higher priority to function correctly.
These types of processes are used to execute tasks where the user does not need immediate results, like data backups, system updates, or other maintenance tasks that can run without direct user intervention.
