Windows Interview Question:
What is the important aspect of a real-time system or Mission Critical Systems?
Submitted by: AdministratorA real time operating system has well defined fixed time constraints. Process must be done within the defined constraints or the system will fail. An example is the operating system for a flight control computer or an advanced jet airplane. Often used as a control device in a dedicated application such as controlling scientific experiments, medical imaging systems, industrial control systems, and some display systems.Real-Time systems may be either hard or soft real-time.
Hard real-time:
Secondary storage limited or absent, data stored in short term memory, or read-only memory (ROM) Conflicts with time-sharing systems, not supported by general-purpose operating systems.
Soft real-time:
► Limited utility in industrial control of robotics
► Useful in applications (multimedia, virtual reality) requiring advanced operating-system features.
