According to the context in which it is used, the word class can refer to various questions ... For Biology, a class turns out to be the taxonomic group that includes several orders, whether of plants or animals, that share many common characters. Meanwhile, for another science, such as Sociology, the class is a type of social stratification that will be carried out taking into account economic criteriaIn other words, in class, a group of individuals share a common characteristic, their productive function or economic power, which will link them socioeconomically. The most common classification in which the population falls to be divided is according to the wealth they possess and the following social classes are proposed to us: upper class, middle class and lower class.
In the upper class will be located all those individuals who within a society are those who have more power and wealth, that is, in our current conception within this class will be located the owners of large companies, those individuals who occupy in some company some hierarchical position and that therefore brings them succulent economic income. But those people who have high levels of political influence will also be considered as part of this class, because of course, politics is always in close association with the economy.
The middle class, for its part, will be made up of that portion of society that is precisely at the middle level, between the upper class and the lower class. This social class is characterized by living on their income or the income they receive from their work. Normally made up of professionals, the middle class is considered by many to be the economic engine of societies.
And the lower class is that social sector that has been more relegated in relation to the previous two. It is in which the highest level of poverty and deficiencies is appreciated, that is, most of the people who make up this social class cannot meet their basic needs and therefore in order to survive, in many cases, they demand the assistance of the state through family allowances or allowances.
The lower class is usually represented by those individuals who perform basic tasks or trades such as workers, domestic staff, ordinances, among others, that although they charge a salary for their jobs, it is certainly low in relation to other jobs, and then they must live with more limitations than, for example, professionals, who tend to have better jobs and earn more.
This state of affairs is the usual one, although we must emphasize that in some countries it tends to happen the other way around and professionals are more relegated in relation to people who perform trades or other tasks of lesser importance.
And we must also say that many people who make up the lower class are unemployed people, who do not receive income precisely because of that unemployment situation in which they find themselves.
Use in computing and logic
In another vein, for computer science, a class is a declaration or abstraction of objects, something like the definition that is carried out of an object. When the object is programmed, its characteristics and functions must be defined, so what is being done is programming a class. The class in this sense contains one or more data, together with the operations that manipulate it.
On your side, Logic, says that the class a property that allows the meeting in a unit or the definition in a collection of those individual elements that are presented to us and we want to group, order according to their similarities.
Room in which the teacher teaches and the students learn
On the other hand, in the academic fieldThe term class turns out to be very popular and is mostly used in two senses; on the one hand, it will be called class to the physical place, the room, within an educational establishment in which a teacher teaches the lessons to his studentsFor example, in Spain this use is very recurrent in schools to call the traditional classrooms; but in addition, in this area the word is often used to refer in general terms to the subject that is learned ... "in math class we learned set theory".
Use in the military plane
AND in the military career, a class is those elements promoted to the lower degrees in the hierarchyFor example, corporals and sergeants, who will have direct command functions over personnel who do not have a degree, although they do not have administrative authority or functions.
