Real-time developers are often most concerned with meeting specific time deadlines for tasks. The difficulty in using an operating system for real-time programming is that it must be able to guarantee that the worst-case response time to give control to a process which needs attention is short enough for the process to handle events on time. If the worst-case response time of the process is greater than its deadline, then the scheduling is not feasible. One strategy to ensure efficient response time is to prioritize processes so that more important processes always receive processor attention if they need it.
