What is real-time OS with example?

A real-time operating system (RTOS) is an operating system that guarantees a certain capability within a specified time constraint. For example, an operating system might be designed to ensure that a certain object was available for a robot on an assembly line.

What is RTOS give an example?

A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time applications that process data as it comes in, typically without buffer delays. … A real-time system is a time-bound system which has well-defined, fixed time constraints.

Where are RTOS used?

Real-time operating systems are commonly found and used in robotics, cameras, complex multimedia animation systems, and communications. RTOS is frequently used in cars, military, government systems, and other systems that need real-time results.

How RTOS is different from General Os?

In general, an operating system (OS) is responsible for managing the hardware resources of a computer and hosting applications that run on the computer. An RTOS performs these tasks, but is also specially designed to run applications with very precise timing and a high degree of reliability.

Why RTOS is required?

An RTOS will often be used when there are more interrupt sources, more functions, and more standard communications interfaces that need to be supported. If the application is <64KB in size, an RTOS is not necessary. Conversely if, the applications is 1 MB, an RTOS will likely be used.
