ESRI shapefiles are a simple, non-topological format for storing the geometric location and attribute information of geographic features.

The shapefile format defines the geometry and attributes of geographically-referenced features in several files with specific file extensions that are stored in the same folder on disk.

They are:

.shp - the file that stores the feature geometry.
.shx - the file that stores the index of the feature geometry.
.dbf - the dBASE file that stores the attribute information of features.

See http://www.esri.com for more information regarding this format.
