In biological classification, class (Latin: classis, 纲) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank.[a] Other well-known ranks in descending order of size are life, domain, kingdom, phylum, class, order, family, genus, and species.
A social class [阶层] is a set of concepts in the social sciences and political theory centered on models of social stratification which occurs in class society, in which people are grouped into a set of hierarchical social categories, the most common being the upper, middle and lower classes. Stratification is the division of something, especially society, into different classes or layers.
The working class (or labouring class) comprises those engaged in waged or salaried labour, especially in manual-labour occupations and industrial work. Working-class occupations (see also "Designation of workers by collar color") include blue-collar jobs, some white-collar jobs, and most pink-collar jobs. Members of the working class rely exclusively upon earnings from wage labour; thus, according to more inclusive definitions, the category can include almost all of the working population of industrialized economies, as well as those employed in the urban areas (cities, towns, villages) of non-industrialized economies or in the rural workforce. A pink-collar worker is someone working in the care-oriented career field or in fields historically considered to be women’s work. This may include jobs in the beauty industry, nursing, social work, teaching, secretarial work, or child care.
A ship class is a group of ships of a similar design. This is distinct from a ship type,[1] which might reflect a similarity of tonnage or intended use. For example, USS [United States Ship] Carl Vinson is a nuclear aircraft carrier (ship type) of the Nimitz class (ship class).
A travel class is a quality of accommodation on public transport. The accommodation could be a seat or a cabin for example. Higher travel classes are designed to be more comfortable and are typically more expensive. China Railway High-speed (CRH) EMUs offer the following classes: soft sleeper (available only on few overnight routes), business seat, 1st class seat and 2nd class seat. EMU stands for Electric Multiple Unit and is a type of passenger train where most or all of the carriages has its own electric motor negating the need for a regular locomotive to provide traction.
Vehicle size classes are series of ratings assigned to different segments of automotive vehicles for the purposes of vehicle emissions control and fuel economy calculation. Various methods are used to classify vehicles; in North America, passenger vehicles are classified by total interior capacity while trucks are classified by gross vehicle weight rating (GVWR).
