Real Time
In business, a system is described as real-time if it will operate in a deterministic manner, i.e., it will respond to input within a defined time limit. For example, safety-relevant systems must always respond within pre-determined time limits. Many automation applications are also real-time, as unpredictable response times and reaction delays would effectively destabilize the process. To ensure a system is real-time, it must fulfill stringent demands with both hardware and software design.

Repeatability
Repeatability: The closeness of agreement between the results of successive measurements of the same measured, carried out under the same conditions of measurement, i.e.: by the same measurement procedure; by the same observer; with the same measuring instruments, used under the same conditions; at relatively short intervals of time. [IEC 60050-300]
