Geographic information is information that has some spatial component, usually in relation to the earth. The information is stored in spatial co-ordinates and can be one of a variety of geometries, such as a single point, a line of points or an enclosed line of points such as a polygon.
A geographic information system can support spatially referenced information. Many kinds of information can have a spatial component. A geographic information system is capable of understanding the spatial nature of the information and provides functionality that supports it.
For example, a dataset of national parks in a non-geographic system has no awareness of the geographical position of the park. In a geogrpahical information system the geometry of the park and its spatial location on the earth can be described. With this kind of information the parks can be queried and compared based on geographic properties, such as:
Geographic information systems can often also visualise geographic data: for instance, Google Maps can display the geometry of road information.

"Geografisch informatiesysteem" is a Dutch equivalent of "geographic information system" (GIS).

"Sistema de Información Geográfica" is a Spanish equivalent of "geographic information system" (GIS).
"Sistema de informação geográfica" is a Portuguese equivalent of "geographic information system."
By definition, a geographic information system (GIS) is a computer application used to store, view, and analyze geographical information. Google Earth is such a system.
Geographic Information System (GIS) is the name for a computer-based system that stores and uses information linked to geographic locations. It allows users to analyze, visualize, and interpret spatial data for various purposes such as mapping, planning, and decision-making.
A geographic information system differs from other computerized information systems in two major respects. First, the information in this type of system is geographically referenced (geocoded). Second, a geographic information system has considerable capabilities for data analysis and scientific modeling, in addition to the usual data input, storage, retrieval, and output functions.A geographic information system is composed of software, hardware, and data. The notion of data layer (or coverage) and overlay operation lies at the heart of most software designed for geographic information systems.
That could be a Geographic Information System. That could also be a GPS device.
A geographic information system can tie a digital map to a database. The geographic information system is called the GIS. It may also tie real-time photos to the map to help with things like GPS navigation.
