The process of sorting things into groups with similar characteristics is called classification. Classification involves organizing items, objects, or data into categories based on shared attributes or properties. This method is widely used in various fields such as biology, library science, and data management to make information more accessible and easier to understand.
For example, in biology, organisms are classified into different groups like kingdoms, phyla, and species based on their physical and genetic characteristics. In everyday life, classification helps in organizing items like books in a library or products in a store, making it easier to locate and manage them.
