It is known as parameter to the fact which is considered as essential and indicative in order to evaluate or evaluate a certain situation. From a parameter, a certain circumstance can be understood or placed in perspective. To give some concrete examples: “If we rely on the usual parameters, it will be impossible to understand this situation”, "The patient is evolving according to the expected parameters", "We are investigating but there are no parameters that allow us to establish a relationship with the previous case", “The performance of the team in the local tournament is the best parameter to make a forecast about his participation in the world championship ”.

For the field of mathematics, the parameters consist of variables that allow to recognize, within a set of elements, each unit by means of its corresponding numerical value.

A statistical parameter is that formed by a function established on the numerical values ​​of a community . It is, therefore, a representative figure that allows to model a real plane.

The usefulness of the statistical parameters is faced with the difficulty of manipulating a large number of individual data of the same company. This type of parameters allows to obtain an overview of the population and to carry out comparisons and predictions.

In the computing, more precisely in programming, a parameter represents a data that offers a function with a specific purpose. For example, a routine that aims to return the highest number in a list, will expect us to pass this set of values ​​as a parameter to perform its task.

In some languages, it is possible to specify that certain parameters are optional, and assign them a default value in case the programmer chooses not to pass them. In graphics programming, for example, it is usually common for functions or methods that manage color-related topics to have a parameter for transparency It is not mandatory to specify, since commonly the images of a multimedia application are opaque.

This mainly affects practicality when programming, since there are functions that expect 10 parameters, 6 of which are optional, and being forced to complete those spaces with values Null or false every time you want to do without them represents a waste of time.

The parameterization of a database, on the other hand, is the organization and standardization of the information that is entered into a system. In this way, it is possible to carry out different types of consultation and obtain reliable results.

The parameterizable design is usually the best option when developing any type of computer application, database, web page, etc., since it consists of a flexible creation, which can be modified without rewriting. The degree of parameterization can vary depending on several factors, the most important being the capabilities of the development environment used and the creativity of the programmers.

In the first case there are limitations such as tasks that a certain language or engine is not able to perform at runtime or even compilation. An example is a video game development kit that is unable to change the resolution once it works, forcing the developer to specify that value only once. before starting the Program.

If a programmer has a detached view of the conventional, provided he has the right knowledge and means, he can find extremely flexible and adaptable designs. For example, an ideal programmable program would be able to adjust all its elements to any aspect of the screen, adapt to a specified framerate (number of frames per second) without altering the speed of the animations, and even dynamically load code that serves to alter its operation once compiled.
