Describe classification
What will be an ideal response?
The simplest way to describe a class is to say that it results from classification, which is the result of two simultaneous mental activities: abstraction and generalization. Abstraction is identifying those characteristics of an entity that distinguish it from other kinds of entities. When classifying objects, we select those attributes and operations which we consider to be significant or relevant to the concept. To generalize is to conclude that the characteristics of a particular entity apply to a broader range of entities. If we cannot apply what we have abstracted to more objects than one, we would not have a class. If there were only one telephone in the entire world, it would be not only useless, but also unclassifiable: a class must apply to a set of objects that share a set of selected attributes and/or operations.
