## What Does parameter Mean

It is known as a parameter to the data that is considered essential and indicative to be able to evaluate or assess 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 patient. previous case " , " The performance of the team in the local tournament is the best parameter to make a forecastabout his participation in the world championship ” .

For the field of mathematics , the parameters consist of variables that allow recognizing, within a set of elements, each unit by means of its corresponding numerical value.
A statistical parameter is one formed by a function established on the numerical values ​​of a community . It is, therefore, a representative figure that allows a real plane to be modeled.
The usefulness of statistical parameters lies in the difficulty of manipulating a large number of individual data from the same society. This type of parameter allows you to obtain an overview of the population and carry out comparisons and predictions .
In computing , more precisely in programming, a parameter represents a piece of data that is offered a function for a specific purpose. For example, a routine that aims to return the highest number in a list will wait for us to pass that 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 common for functions or methods that handle color-related issues to have a parameter for transparency that is not required to be specified, since images in a multimedia application are commonly opaque.
This mainly affects the practicality when programming, since there are functions that expect 10 parameters, 6 of which are optional, and being forced to fill those spaces with null or false values 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 in a system . In this way, it is possible to carry out different types of queries 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 the need to rewrite . 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 capable of performing at runtime or even compilation time. An example is a game development kit that is unable to change the resolution once running, forcing the developer to specify that value only once before starting the program .
If a programmer has a vision detached from the conventional, provided he has the right knowledge and means, he can come up with 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 how it works once compiled.
