What is a real-time system model?
A real-time system means that the system is subjected to real-time, i.e., the response should be guaranteed within a specified timing constraint or the system should meet the specified deadline.
For example flight control systems, real-time monitors, etc..
What is the basic model of a real-time system?
A real-time system takes inputs through sensors, and other external input devices, then processes these input signals in real-time to produce output.
Therefore, a real-time system is implemented with the help of a variety of hardware components and software applications..
What is the difference between hard RTS and soft RTS?
A hard-real time system is a system in which a failure to meet even a single deadline may lead to complete or appalling system failure.
A soft real-time system is a system in which one or more failures to meet the deadline are not considered complete system failure, but that performance is considered to be degraded..
What is the real-time software design method?
A real-time system is a software system where the correct functioning of the system depends on the results produced by the system and the time at which these results are produced.
A soft real-time system is a system whose operation is degraded if results are not produced according to the specified timing requirements..
- A real-time operating system (RTOS) is an operating system with two key features: predictability and determinism.
In an RTOS, repeated tasks are performed within a tight time boundary, while in a general-purpose operating system, this is not necessarily so. - Examples of real-time operating systems are airline traffic control systems, Command Control Systems, airline reservation systems, Heart pacemakers, Network Multimedia Systems, robots, etc.
Hard Real-Time Operating System: These operating systems guarantee that critical tasks are completed within a range of time.
