a realtime system is one that must react to inputs with outputs in real time. at the simplest this means the system must meet deadlines. there are 2 types of realtime systems:
- soft realtime systems only have to meet deadlines on the average, its OK to occasionally miss a deadline the system will still keep functioning. such systems typically only interact with people. if the system misses too many deadlines the people get irritated with its slowness, but the task still gets done.
- hard realtime systems must meet all deadlines, missing a single one means the system has failedto perform the function it was designed for. such systems are typically used to control other equipment; some examples of realtime systems are: industrial process controllers, aircraft flight control systems, missile guidance systems, spaceprobe guidance and control systems, experiment data collection controllers, etc. in each of these cases missing even one deadline could result in a catastrophic failure (with possible loss of life) or permanent loss of data from an experiment costing many millions of dollars to setup.

Is Linux are real time operating system?
It can be. The kernel has a real time process scheduler, and there's a popular real time patchset that is often used to modify the kernel to be a more dedicated real-time system.
Distinguish between batch system real time system multi tasking system?
The difference between Batch System, Real Time System and Multitasking System is that they are cool and you are a gimp.
Difference between Hard real time system and soft 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
What is relation between settling time and real roots of a system?
Settling Time and the Real roots of a system are related reciprocally.
Types of real-time systems?
There is 2 type of real-time system a) Soft real time system ->partially meet the deadline means can do the round of the time to meet the dead line. b) Hard real time system -> Strictly meet the deadline. Thanks & Regards Ajay Gautam
What is the purpose of RMX operating systems?
A RMX operating system is a real time operating system that is specifically for two families of processors. This real time system can be used on applications that need real time reliability, determinism and more.
What is response time in real time system and What is the difference between response time and execution time in real time system?
response time is the time in which our system respond us back, i.e. the system gives us the result of our input at what rate.. and execution time is the time taken by the system to complete the input... if the response time of our system is high then the performance of the system is not accurate..
What is a real time operating system used for?
Real Time Operating System (RTOS) aims to serve real time requests. It aims to be fast and not encounter buffering delays on applications and software.
Which operating system reads and reacts in terms of actual time?
Real time system
What are the disadvantages of real-time operating system?

When Real-Time System are required?
Real-time systems are required in situations when real-time processing is needed or intense calculations need to be done.
Main difficulties in writing an operating systems for a real time environment?
The main difficulty is keeping the operating system within the fixed time constraints of a real-time system. If the system does not complete a task in a certain time frame, it may cause a breakdown of the entire system it is running. Therefore when writing an operating system for a real-time system, the writer must be sure that his scheduling schemes don't allow response time to exceed the time constraint.
