Which of the following is a key feature of priority scheduling in data processing?

Priority scheduling is a method used in operating systems and data processing that determines the order in which tasks are executed based on their importance or priority level. Choosing tasks with higher priority ensures that critical processes receive the necessary CPU time and resources they require when they need them most.

High responsiveness is a key feature of this scheduling method because it allows systems to quickly react to urgent tasks, ensuring that high-priority processes are completed efficiently and promptly. This responsiveness is especially important in real-time systems where delays can lead to significant issues or failures.

The other features listed, while relevant to different scheduling or resource management approaches, do not accurately capture the essence of priority scheduling. For example, even distribution of tasks focuses more on load balancing rather than prioritizing tasks based on urgency. Similarly, resource utilization might refer to optimizing the use of available resources but does not inherently take task priority into account. A strict order of operations implies a predetermined sequence that does not allow for flexibility based on priority, which is contrary to the nature of priority scheduling.
