Embedded systems are used to give the response in real time. So, it consists of the real time systems that allow the correct information to be passed to get the correct responses. For example, it includes of the flight control system that produce the responses in real time and it always the take the values also in real time. If any delay been caused by the system then it deals in the fatal error. The real time system includes the system that provides the response on time with the small delay. Real time systems include of many other system such as:

Hard Real-Time Systems - These are the systems that server the purpose of having constraints that are hard and it totally depends on the time to provide the response on time.

Soft Real-Time Systems - These systems serves the purpose of having few delays in giving up the responses that can tolerate small variations.

Hybrid Real-Time Systems - These systems includes the properties from both the systems and increases the performance.
