5. The Purpose of GIS
The three important stages of working with geographic data:
Data preparation and entry: The early stage in which data about the study phenomenon is collected and prepared to be entered into the system.
Data analysis: The middle stage in which collected data is carefully reviewed, and, for instance, attempts are made to discover patterns.
Data presentation: The final stage in which the results of earlier analysis are presented in an appropriate way.

6. GIS Definition
A geographic information system as a computerized system that facilitates the phases of data entry, data analysis and data presentation especially in cases when we are dealing with georeferenced data.
A similar definition:
A system of hardware, software, data, people, organizations and institutional arrangements for collecting, storing, analyzing, and disseminating information about areas of the earth.
