Real-time system

Real-time systems are those which are intended to interact with the 'real world', and need to meet timing constraints originating with the real-world events they are controlling or observing.

Such systems usually contain schedulers which can guarantee that a given computational element (be it a process or a task) is executing before a certain real-time deadline - hence their usual name, deadline schedulers.
