Category

A category is a group or division in a system of classification. It's a way of organizing and classifying things, concepts, or information based on shared characteristics, attributes, or purposes. Categories allow for easier understanding, comparison, and retrieval of information. This grouping helps to establish relationships between different items within a defined scope. Categories can be broad and general, or narrow and specific, depending on the needs of the classification system. They are fundamental to organizing knowledge, from the Dewey Decimal System used in libraries to the taxonomical classification of living organisms. It is also the primary method by which websites sort their information.
