ject can be characterized by answering the basic question: "What can the given object do?" This question characterizes the concept of the "result of action of an object" which in turn consists of two subquestions: What action can be done by given object? (The quality of result of action); How much of such action can be done by the given object? (The quantity of result of action). These two subquestions characterize the aspiration of a system to implement the goal. And the goal-setting may be characterized by answering another question: "What should the given object do?" which also consists of two subquestions: what action should the given object do? (The quality of the result of action); how much of such action should the given object do? (The quantity of the result of action). These last two subquestions are the ones that determine the goal as a task (the order/command, the instruction) for the given object or group of objects, and the system is being sought or built to achieve this goal. The closer the correspondence between what should and what can be done by the given object, the closer the given object is to the ideal system. The real result of action of the system should correspond to preset (expected) result. This correspondence is the basic characteristic of any system. Wide variety of systems may be built of a very limited number of elements. All the diverse material physical universe is built of various combinations of protons, electrons and neutrons and these combinations are the systems with specific goals/purposes. We do not know the taste of protons, neutrons and electrons, but we do know the taste of sugar which molecular atoms are composed of these elements. Same elements are the constructional material of both the human being and a stone. The result of the action of pendulum would be just swaying, but not secretion of hormones, transmission of impulse, etc. Hence, its goal/purpose and result of action is nothing more but only swaying at constant frequency. The symphonic orchestra can only play pieces of music, but not build, fight or merchandize, etc. Generator of random numbers should generate only random numbers. If all of a sudden it starts generate series of interdependent numbers, it will cease to be the generator of random numbers. Real and ideal systems differ from each other in that the former always have additional properties determined by the imperfection of real systems. Massive golden royal seal, for example, may be used to crack nuts just as well as by means of a hammer or a plain stone, but it is intended for other purpose. Therefore, as it has already been noted above, the concept of "system" is relative, but not absolute, depending on correspondence between what should and what can be done by the given object. If the object can implement the goal set before it, it is the system intended for the achievement of this goal. If it cannot do so, it is not the system for the given goal, but can be a...
