A Real Time Operating System (RTOS) comprises of two components, viz., "Real-time" and "Operating system". Real-time systems are those systems in which the correctness of the system depends not only on the logical result of computation, but also on the time at which the results are produced. RTOS are those which must produce correct responses within a definite time limit. A RTOS is any information processing system that has to respond to externally generated signal within a finite and specified period. It is a computer system where the correct functioning of the system depends on the results produced and the time at which they are produced.
