"GIS is an integrated system of computer hardware, software, and trained personnel linking topographic, demographic, utility, facility, image and other resource data that is geographically referenced." - NASA
This is probably the most asked question posed to those in the Geographic Information Systems (GIS) field and is probably the hardest to answer in a succinct and clear manner.

What is Java anyway?
The official language definition given in the preface to the Java Programming Language Specification is:
"The Java programming language is a general-purpose concurrent class-based object-oriented programming language, specifically designed to have as few implementation dependencies as possible. It allows application developers to write a program once and then be able to run it everywhere on the Internet." Preface, The Java Language Specification, 2nd Edition
These two sentences say a lot, but I will focus on two important language features: objects and "write once, run anywhere" (WORA).
