You can then use the additional information to query your data in new ways.
 

What is the difference between a spatial join and an attribute join?

Join by location, or spatial join, uses spatial associations between the layers involved to append fields from one layer to another. Spatial joins are different from attribute and relationship class joins in that they are not dynamic and require the results to be saved to a new output layer.

What is the difference between spatial join and join in ArcMap?

Summary: One of the most useful kinds of analysis journalists can do with ArcMap is what Arc calls a spatial join. A spatial join is similar to a join in a database program, except that instead of joining two tables based on a common field you join them based on geographic location.
