What is GIS? GIS is a systematic integration of Computer Hardware, Software and Spatial Data, for capturing, storing, displaying, updating manipulating and analysing, in order to solve complex management problems. Previously we had paper maps, which were very colourful, but couldn't modify. Then came the computer revolution, where the maps were digitised and stored in digital format as entities (points, lines and areas). Then came the GIS, which made these entities intelligent. It attached a value(attribute) to these entities, with what it actually means in geographical terms.
