Hard Real Time System

A hard real time system guarantees that critical tasks complete on time, even the shortest delay or urgency is not acceptable. Here system should meet the deadline. Missile systems are air traffic control system are best examples of hard real time system.

Soft Real Time System

In this time constraint is less strict. The meeting of deadline is not compulsory for each task, every time. A critical real time task gets priority over other tasks until it completes i. it does not guarantee that task will be completed in defined time but before a certain time and according to the priority. Online transaction system, airline ticket reservation in which reservation could be delayed by should be done after checking available seats and competed before aeroplane flight, etc. are examples of soft real time system.
