What do you mean system ? How to form a system? Why are systems called system? What is the system of professional classification research │ system home?

　　The word system is created in the transliteration of English systems , which is rich in foreign language connotation. The system refers to the whole that the scattered things are organized and arranged in order to form the whole.

In the theory of digital signal processing, the entities that can process and transform digital signals are called systems. Since the system that processes the digital signal processes the signal at a specified time or timing, the system is considered discrete time and can be described in four ways, such as time-based languages, tables, formulas, waveforms, and so on.
In the abstract sense, both the system and the signal can be considered as sequences. However, the system is a signal processing mechanism, which is different from the signal. The research system also needs to design the system, uses the system processing signal, serves the human, the system also need other methods to describe further. The methods for describing the system are symbolic, unit impulse response, difference equations, and graphs.

Qian Xuesen, a Chinese scholar, believes that the system is a combination of several components that interact with each other, has a specific function, and the organic whole is part of a larger system that is subordinate to it.

Four classifications of the system:

Natural systems

The individual in the system exists or evolves according to the laws of nature, producing or forming a group of natural phenomena and characteristics.
Natural system includes ecological balance system, life organism system, celestial system, material microstructure system, social system and so on.
Artificial systems

Individuals within the system operate according to human, pre-programmed rules, or planned directions, to achieve or complete functions, performance, and results that individual individuals in the system cannot achieve alone.
The artificial system includes stereoscopic imaging system, production system, traffic system, power system, computer system, education system, medical system, enterprise management system and so on.
Composite systems

A composite system is a combination of natural and artificial systems.
The compound system includes the navigation system, the traffic management system and the man-machine system and so on.
In the process of creating cybernetics, wiener regarded the communication and control of animals and machines as a system.
In order to clarify the object of the study, the object is defined as the system by artificially separating the material or space from the rest of the material or space.
In thermodynamics, a certain mass of gas is usually used as the object of study, which is called system
In fluid mechanics, the collection of many fluid particles is called a system
The human body is composed of eight systems, such as motion system, nervous system, endocrine system, circulatory system, respiratory system, digestive tract, urinary systems and reproductive systems.
