Answer:
Real-time operating system
Explanation:
A real time operating system (RTOS) is built to make sure that work is done within an agreed and specified time constraint. It is able to give a multitasking impression and carry out tasks more rapidly. Unlike the normal operating systems where we are not sure about the exact time the task will be complete, RTOS provides a specific time. As a result, users are able to determine and react to external events. RTOS is programmed to offer support to systems that need to be made available at a specific time and is designed to terminate with failures if it does not.
