问题 A real—time operating system(RTOS)is an operating system intended to serve (71) application process data as it comes in，typically without buffering delays．A key (72)  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  (73)jitter than a soft real—time operting 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．(74) 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 (75)latency and minimal thread swishing latency．
