This means that tasks that are more likely to complete quickly are given higher priority than tasks that are more likely to take a long time to complete. This can be useful for real-time applications, where it is important to ensure that tasks are completed within a certain time frame.<\/p>\n<p>Option A is incorrect because feedback queues can be difficult to implement.
