Excerpt from Wikipedia:

The Esri Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by Esri as a (mostly) open specification for data interoperability among Esri and other software products.

Shapefiles spatially describe geometries: points, polylines, and polygons. Each item may also have attributes that describe the items.

A "shapefile" is actually a set of several files. Three individual files are mandatory to store the core data that comprises a shapefile: .shp, .shx, .dbf
