| progr. | finite state reactive systems | реагирующие системы с конечным числом состояний (ssn) |
| progr. | language for programming reactive systems | язык программирования систем реального времени (Reactive systems interact continuously with their environment, at a speed imposed by the environment; a typical example is the automatic flight control system of modern airplanes. Reactive systems must react to stimuli from the environment within strict time bounds. For this reason they are often also called real-time systems Alex_Odeychuk) |
| softw. | reactive system | система реального времени (interacts continuously with its environment, at a speed imposed by the environment; a typical example is the automatic flight control system of modern airplanes. Reactive systems must therefore react to stimuli from the environment within strict time bounds. For this reason they are often also called real-time systems, and are found often in embedded systems Alex_Odeychuk) |
