Tester's Quiz: What is Equivalence Partitioning Technique?

Most of you have heard this term "Equivalence Partitioning Technique". It is one of the common techniques associated with black box test design techniques (under Domain Testing techniques). Today's Quiz on my blog is related to this...

Explain in 4-5 sentences or less about "Equivalence Partitioning Test design Technique" and provide an example that illustrates the technique (avoid examples like "login" screen)

Notes:
I would also appreciate lots of "context" specific questions like "Who is asking?", “Why 4-5 sentences” etc …

I will consolidate all comments and questions and make another post later....
I am also looking for "real life" experiences of applications of this technique....

Some background:
One motivation for me to present this to my blog readers is my own experiences of discussing in various job interviews (where I was the interviewer) and lots of informal discussions with people. In my experience, lots of testers (especially in India) seem to have a very narrow view of this technique. Most of them have admitted that "it is a theoretical technique - useful only in interviews... etc"

What would happen next?

I would like to de-mystify this stuff (with your views, questions and opinions) and present to you my version of EQ partitioning technique in a blog post....
