GIS, or Geographic Information System, manages, and analyzes data tied to spatial or geographical location.
Vector data is one way that real world features and concepts are represented in GIS.
Let's take a look at vector data
Map of time zone boundaries
Point date is discrete and doesn't immediately border other data. Point data has zero dimensions - you can't measure area or length. Examples: points of interest, cities on a small scale map, trees, elevation points
Line data is used to represent linear features. Line data has one dimension - you can measure length. Examples: roads, rivers, tornado tracks, hurricane paths, borders
Polygons are used to represent areas. Polygons are two-dimensional so you can use this data to measure area and perimeter. Examples: lakes, urban areas, parks, glaciers, countries, states, provinces
