Explain real time operating system.
Answers
Explanation:
A real-time operating system (RTOS) is an operating system that works in real time, with deterministic constraints that require efficient time usage and power to process incoming data and relay the expected results without any unknown or unexpected delays. RTOS software is time dependent, meaning that it should process input and offer output within a short predetermined deterministic period. However the key to an RTOS, and the most important demand of RTOS software is that a request and response for data is guaranteed to occur. If a Windows OS has request and response calls that are fast 90% of the time, yet the remaining 10% of the time an input/output request takes too long, then the real-time application is not performing correctly. Thus an RTOS is not meant to be only fast, it is more importantly meant to be dependable
