Explain Real Time Operating System?
Real time operating System:
A real-time operating system has suitably-defined, fixed time constraints. Processing should be done in the defined constraints or else the system will fail. A real time system is seems to function correctly only if this returns the accurate result in any time constraints. Therefore the following features are desirable in a real-time operating system (OS):
1. Multi-tasking in an application
2. Capability to define the priorities of tasks
3. Priority deadline or driven oriented scheduling
4. Programmer defined interrupts.
