Feedback is a process by which a system, can be of any type, receives energy provided by itself in order to guarantee its operation. Let's draw an imaginary line with a point A and a point B, the energy, the fluid or the product advance from A to B, but if a mechanism is created so that for that same product generated by a, it returns again to its origin e drive a constant current, effective feedback will be generated. The application of this definition can be found in engineering, chemical and physical processes that generally use mechanisms to optimize work.
Its application in other less technical aspects turned the term into a study tool, because the feedback of information serves to guide knowledge between certain points of a relationship. An example of Feedback from the field of today, the company launches its advertising campaign of its product to customers, to measure the response of people to it, they conduct field research on social networks, to determine How did it turn out, whether they liked it or not, thus generating a matrix of information and data as a result of the feedback generated between the public and social networks and the company with social networks.
Feedback is a dynamic tool that is practical because it synthesizes the search for content. It is related in the society that uses it with feedback, because this is like a control of the understanding of a relationship. When there is feedback, it is understood that there is a concordance between the systems involved. In other words, the system itself understands the procedure to be carried out by all the components.
There are two types of feedback, positive and negative, positive implies that what is "fed back" generates increase, this variation will make the system work better and faster. The negative feedback is when the initial system produces necessary force or thrust so the system that complements the stable driving energy, preventing this desmejore or disappear.
