The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products.The shapefile format can spatially describe vector features: pointslines, and polygons, representing, for examplewater wellsrivers, and lakes. Each item usually has attributes that describe it, such as name or temperature.

First of all, despite the singular name, it’s not just one file.  A shapefile is actually a GIS vector data format that has, at a minimum, three mandatory files.  These three file contain the necessary information about the geometry (.shp)  and attribute (.dbf) information for the GIS dataset as well as an index file (.shx).  As noted, there are additional optional files that can be attached to a shapfile such as a .prj file which stores the file’s coordinate system information.
