A real-time operating system (RTOS)[Generally pronounced as: Or-tos] is a multitasking operating system intended for real-time applications. Such applications include embedded systems (programmable thermostats, household appliance controllers, mobile telephones), industrial robots, spacecraft, industrial control (see SCADA), and scientific research equipment. An RTOS facilitates the creation of a real-time system, but does not guarantee the final result will be real-time; this requires correct development of the software. An RTOS does not necessarily have high throughput; rather, an RTOS provides facilities which, if used properly, guarantee deadlines can be met generally (soft real-time) or deterministically (hard real-time). An RTOS will typically use specialized scheduling algorithms in order to provide the real-time developer with the tools necessary to produce deterministic behavior in the final system. An RTOS is valued more for how quickly and/or predictably it can respond to a particular event than for the given amount of work it can perform over time. Key factors in an RTOS are therefore a minimal interrupt latency and a minimal thread switching latency. An early example of a large-scale real-time operating system was Transaction Processing Facility developed by American Airlines and IBM for the Sabre Airline Reservations System.

What is the purpose of RMX operating systems?
A RMX operating system is a real time operating system that is specifically for two families of processors. This real time system can be used on applications that need real time reliability, determinism and more.
What are three types of operating systems?
Mac OS X, Linux, and Microsoft Windows are three types of operating systems. Single-user, multi-tasking, multi-user, and real-time operating systems, or RTOS, are different types of operating systems that computers use.
Real time examples for batch operating system?
Explain the key characteristics of the following forms of operating systems i) Batch
What is the main difficulty that a programmer must overcome in writing an operating system for real-time environment?
First, they have to spend a couple of years with learning the theory and practice of operating systems, and another couple of years with mastering real-time systems.
Are Palm OS Windows CE and Linux real-time operating systems?
Palm OS is generally not considered a real-time operating system. True real-time operating systems are multi-tasking; the "real-time" refers to the ability to effectively manage resources to achieve a result in as little time as possible. Palm OS is single-tasking, so the speed at which it performs is mostly bottlenecked by the individual application running. Windows CE is a real-time operating system; most uses of it are in multi-tasking devices. Linux is not necessarily a real-time operating system, but can be configured that way, depending on the scheduler selected.

Do machines with built in computers use real time operating systems?
Yes, most machines with built-in computers that perform a sequence of tasks in a precise amount of time require a real-time operating system ( or RTOS ).
What is an example of a real-time operating system?
there are: • bookings (any) • games • control process (any) • safety critical systems • any other suitable example
QNX operating systems is used for what purpose?
The QNX operating system is mostly used for industrial purpose. It is a real time Operating system as opposed to Linux that is considered a basic operating system.
