Absolute location is the actual spot on the planet where something is. A good example would be the latitude and longitude of a place. For instance, Lake Maracaibo of Venezuela is at 10°39' N latitude and 71°36' W longitude.

Absolute location can also be the exact spot where something is within a city, such as saying that the city hall is at Fifth and D street.

Absolute location: the exact position of an object or place, measured within the spatial coordintes of a grid system.(Barron's : How to prepare for the AP Human Geography exam)

Absolute location is the polar opposite of relative location, which is where something is in relation to something else.
