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抯 task; the variability is jitter. A hard real-time operating system has (73) 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. (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 switching latency.
