Real Time System : There is also a Operating System which is known as Real Time Processing System. In this Response Time is already fixed. Means time to Display the Results after Possessing has fixed by the Processor or CPU.
Real Time System is used at those Places in which we Requires higher and Timely Response. These Types of Systems are used in Bomb and Reservation. So When we Specify the Request , the CPU will Perform at that Time. There are two Types of Real Time System
A Hard Real-Time System guarantees that critical tasks complete on time. This goal requires that all delays in the system be bounded from the retrieval of the stored data to the time that it takes the operating system to finish any request made of it.
A Soft Real Time System where a critical real-time task gets priority over other tasks and retains that priority until it completes. As in hard real time systems kernel delays need to be bounded.
