RTOS: Real-Time Operating System
Real-time operating system (RTOS) is an operating system designed specifically for use in real-time systems and applications. Examples include embedded applications (programmable thermostats, household appliance controllers, mobile telephones), industrial robots, industrial control, and scientific research equipment. A real-time operating system does not necessarily have high throughput — the specialized scheduling algorithm and a high clock-interrupt rate can both interfere with throughput. That is to say, RTOS are valued more for how quickly they can respond to input than for the total amount of work they can do.
