What are the characteristics of real time operating system?
A real-time operating system has certain distinguishing characteristics.
The term is used ambiguously due to the varying time constraints for real-time systems.
For instance, a real-time system needs an application to meet the average deadlines of a set time with minimal variability while processing an external event.

What is a real time operating system and how does it work?
The scheduler in an RTOS is designed to provide a predictable execution pattern, scheduler uses priority to know which thread of execution run next. The kernel is the central part of an operating system and kernal is responsible for the inter task communication, task management and task synchronization.

What is real system?
A real time system is a time bound system which has well defined fixed time constraints. Processing must be done within the defined constraints or the system will fail. They either are event driven or time sharing.
What is normal operating system?
Real-time operating systems are also known as multitasking operating systems. The normal operating system is responsible for managing the hardware resources of a computer. The RTOS perform these tasks, but it is especially designed to run applications at a scheduled or precise time with high reliability.
What is task RTOS?
A task can exist in one of the following states: Running. When a task is actually executing it is said to be in the Running state. It is currently utilising the processor. If the processor on which the RTOS is running only has a single core then there can only be one task in the Running state at any given time.

What is considered real time?
In computer science, real-time computing (RTC), or reactive computing describes hardware and software systems subject to a “real-time constraint”, for example from event to system response. Real-time responses are often understood to be in the order of milliseconds, and sometimes microseconds.
What are real time applications?
A real-time application (RTA) is an application program that functions within a time frame that the user senses as immediate or current. The latency must be less than a defined value, usually measured in seconds. The use of RTAs is called real-time computing (RTC).

Why are embedded systems called real time systems?
Another name for many of these systems is reactive systems, because their primary purpose is to respond to or react to signals from their environment. A real-time computer system may be a component of a larger system in which it is embedded; reasonably, such a computer component is called an embedded system.
