This is an introduction to systems. It is a fundamental part of cybernetics, since we need to understand what a system is in order to create one by programming.

A system is a set of elements that are organized and interact among them, in order to achieve an specific goal through processes and feedback. A systems interacts and has a relationship with its environment.


 * Goal : The system works towards achieving an specific objective. This guides the system itself.
 * Environment : It represents the place, location or scope under which the system operates.
 * Control : This is the command center and regulates the process according to the feedback received. Furthermore, the control regulates the functioning of the system.
 * Input : In this way the system receives commands and information. The input includes all the required materials and input necessary for the operation of the system.
 * Output : The byproducts generated by the system: includes both positive and negative. (waste, results, etc.)
 * Process : The main functioning of the system.
 * Feedback : Responses that the system uses to indicate corrections or the evolution necessary for the system.

A way to illustrate a system is through a computer, since this is an enclosed system that interacts with its environment. People upload and download information using input and output systems. There are several processes within the computer, these are all altered using feedback, and the actions of the user have an effect on the way the procedures mutates. In this way you can operate a simple calculator in your PC.

The pictures below indicates some mediums of input and output for the PC:
