A Real Time Operating System is a class of operating system which is used for real time applications. It is better known by its acronym RTOS. These applications consist of several embedded systems, industrial robots, spacecraft, industrial control and other scientific implements. This system helps in the creation of a real time system but does not ensure that the end-result will be real-time as this depends on several other factors.

Real-time operate in controlled environments in which computer memory and processing power are restricted. They often need to provide their services within strict time deadlines to their users and to the surrounding world. This is made easier with the help of RTOS. It offers services such as intertask communication and synchronization, dynamic memory allocation, task management, device I/O, timers etc. An RTOS uses specialized scheduling algorithms and is most popular for its minimal interrupt latency and a minimal thread switching latency.

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. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter increments of time. For more info get help at
