Function

In general (not in the mathematical but in the engineering sense), a function is a goal-oriented property of an entity. The carrier of a function is a process; therefore, is possible to realise the same function using different physical processes, and one process can be a carrier of multiple functions. For example, the main function of a clock, the presentation of time, can be realized by different physical processes, including atomic, electronic, and mechanical processes. In natural language, the terms process or task are frequently used for the concept.
