A real time operating system hold well defined fixed time constraints. Process has to be done within the defined constraints or the system will fail. An instance is the operating system for a flight control computer or an advanced jet airplane. Frequently used as a control device in a dedicated application such as controlling scientific experiments, industrial control systems, medical imaging systems and some display systems. Real-Time systems might be either hard or soft real-time.
Hard real-time: Secondary storage restricted or absent, data stored in short term memory, or read-only memory (ROM), Conflicts along with time-sharing systems, not supported through general-purpose operating systems.
Soft real-time: Limited utility in industrial control of robotics, Useful in applications (multimedia, virtual reality) needing advanced operating-system features.
Advantages of asynchronous architectures: Asynchronous architectures decouple senders & receivers. It brings about performance advantages for both the sender & the receiver. The sender is capable to even out his communication traffic over the
