What's+a+System?

A **System ** is a group of 2 or more elements that work together to achieve a goal. Each element is a supersystem (in case it envolves two or more elements in itself) and a subsystem by itself. The behavior of each and all of the elements affect the whole system.

A system has different element such as:

**Subystems.-** Can be described as all the elements interacting in the system which enable it to work.


 * Control Mecanisms.- ** Control mechanisms refer to all of the commands and actions the user can execute to change, accelerate, slow or stop the processes in the system.

**Goal.-** The goal is what the system is intended to achieve or produce, it's main objective. 
 * Control.- ** Control refers to the actions the user must do to enable the machine to continue working. I.e. Change gears and steer wheels in a car.

**Process.- ** The process is the series of steps that must be followed to fulfill a goal.

**Feedback.-** The feedback is all the information that can be given in order to improve an element or change it to make it more effective.

An example of a system and supersystem is the human body. In this case, the complete body is the supersystem, understanding it in THIS CONTEXT as the biggest system. This supersystem contains smaller systems inside such as : respiratory, digestive, circulatory, endocrinological and nerves system. Each "smaller" system (respiratory, digestive, circulatory, endocrinological and nerves system. ) has it`s own function and they have interactions between each others.

An example of this is when our stomach (which is a subsystem of the digestive system) is "full", so it has to use the nerves system to let the brain know there is no more food needed.

Another example is that during digestion oxygen is needed in the digestive system to let chemical reactions take place. In this case, the digestive system is deoendent from the oxygen that the respiratoy system can provide.

Now, all the supersystem, as well as each of the subsystems have a goal. In the case of the human body itself, the goal is not to stop functioning, and each subsystem provides with other goals to enable the supersystem to complete it's goal.
