Real Time Operating System

In the real time operating system, the job is to be completed within the rigid time constraints otherwise job lases its meaning. The real time operating system function correctly only of to returns  correct result within its time constraints.

Thus in the real time operating system, the correctness of computation not only depend upon the logical correctness of the computation but also upon the time at which the results in produced.  Real time operating system is used in application like, robotics, air-traffic controls etc.
