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.A.characteristicB.programmingC.structureD.computer
