We say selection or selecting data in reference to both the features we see in the map and the rows found in the attribute table because that is what we are doing: picking out attributes in the table or features in the map, resulting in the rows in the table and the features in the map becoming highlighted, or selected. To pick out only the features we are interested in at that moment, we use three separate but related selection processes: Select by Attribute which uses the values, or attributes, of features to make a selection in the attribute table (or other non-spatial data table), Select by Location which uses spatial relationships and interactions to make a selection, regardless of attributes, and Interactive Selection, where we use a tool in ArcGIS to click on features in the map, resulting in a selection. In GIS, we often have vector data with attributes tables which contain more attributes or features then we need at one time. Probably the most common thing done in GIS is locating and isolating features (shapes to represent real world features and the attributes which accompany them) which match a specific search criteria to help us answer spatial questions.
