We see many objects around us. Some of these objects are natural (which occur in nature), whereas other objects are man-made (artificial, i.e. created by human beings). All these objects are of different shapes, sizes, colours and properties. To understand objects around us, it is essential to classify them. Sorting refers to the method of organising objects in a group (systematic order).
