If we want products with different size options such as X, Xl, XXL and we want to keep stock info for each of the individual sizes separately, then we need to create configurable products and attributes to achieve this.

A Configurable product offers the customers a variety of options, which are selected from drop-down lists. For example, a 'tee shirt' that comes in 'three colors' and 'three sizes' would have two drop-down lists of options for 'Color' and 'Size'. Here the 'Size' & 'colour' are called 'Configurable attributes' and 'tee shirt' as 'Configurable product'.

A Configurable Product is essentially a collection of Simple products which are presented as options in drop-down lists.
