A real-time operating system manages the resources of embedded computers that are controlling ongoing physical processes and that have requests that must be serviced within fixed time constraints. This type of operating system guarantees that it can service these important requests within that fixed amount of time. For example, it may guarantee that, regardless of what else it is currently doing, if an airline collision-detection message arrives, the software implementing collision avoidance will be activated and executed within 50 milliseconds. Typically, the way that this guarantee is implemented is that all requests to a real-time operating system are prioritized. Instead of being handled in first-come, first-served order, they are handled in priority sequence, from most important to least important, where "importance" is defined in terms of the time-critical nature of the request. A real-time operating system lets passengers be uncomfortably cool for a few more seconds while it handles the problem of avoiding a midair collision.
