RTOS is a multitasking operating system for applications that need meeting of time deadlines and functioning in real time constraints.

Features:

• Timeliness- OS has to provide mechanisms for time management and handling tasks with explicit time constraints.
• Predictability- It means to guarantee advanced deadline satisfaction and to notify when deadline cannot be reached.
• Fault tolerance- Hardware or software failures do not cause a crash.
• Design for peak load- All scenarios must be considered.
