A real-time operating system.(RTOS)is an operating system intended to serve( )application process data as it comes in,typically without buffering delays.A key(请作答此空)of a RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application’s task;the variability is jitter.A hard real-time operating system has( )jitter than a soft real-time operating system.The chief design goal is not high throughput,but rather a guarantee of a soft or hard performance category.A RTOS has an advanced algorithm for scheduling.( )flexibility enables a wider,computer-system orchestration of process priorities,but a real-time OS is more frequently dedicated to a narrow set of applications.Key factors in a real-time OS are minimal( )latency and minimal thread switching latency.
