In the ArcGIS Online exercise, we imported layers into ArcGIS Online. In ArcMap, we will work with shapefiles.
The difference between layers and shapefiles is substantial: shapefiles store the data that's related to the attribute of the geographic feature you are using, while layers merely hold the link to the data. This means that you can't edit the layer data in the same way you can edit the shapefile.
