Meaning and Definition of Function

Definition of function

A function refers to the activity or set of activities that can play one or more items at the same time, obviously in a complementary manner, in order to achieve a defined objective.
Although, without a doubt, this activity and objective can occur in different contexts, by which the term of function applies equally in fields such as computer science, mathematical, artistic, technical and semiotic among others.
In the case of the so beloved by some and so hated by other, mathematics, which appeared to us all at some point and on the occasion of the school stage, a function is the correspondence or relationship of the elements of an array "A" with the elements of an array "B". To this end, the progressive complexity of the concept of function in mathematics results in progressive graphics settings, theorems and finally called mathematical analysis, basic substrate from other disciplines including physics and information science.
On the other hand, in the context of computer science, function is a subprogram or subroutine that in addition to execute a specific task, returns a value. In the early days of programming, applets were part of everyday models of diagrams of flow and languages such as C or Basic strategies; Currently, functions that give rise to the subprogrammes are integrated into the main programming environments.
In semiotics, also mentioned above, a function is the set of elements and relationships that exist between them and that are absolutely necessary when defining structures. Thus, understanding the signs and symbols, as well as strategies for its application in advertising or the scientific field would be really impossible without the use of functions.
Meanwhile, when we were talking about a function and gave him an artistic context, we referred to the artistic representations of a play. Under the same scope is cited as "function" to display in other environments, such as the recitals of music, the presentation of a film production or other disciplines of the arts; in this model, it is very common to replace the word function with the anglicism show, many broadcasting today.
And finally, for the technical category, a function is the step, making use of a suitable device, the initial state of the system at the other end state desired. Thus, even applies the idea of function to define a series of physical, chemical, or biological phenomena in a living being. We then speak of cardiac function to refer to the task of the heart as a pump and the multitude of vessels for the transportation of blood. Also noted as a mental function to the capabilities of human beings for memory, the life of relationship, the resolution of problems and other so many facets of our brain activity.
Therefore, functions are part of our daily lives in all areas and procedures imaginable. Perhaps without them, our reality would be very different...
