In which I Explain a commonly used term

So, I was asked, along with my husband, for an explanation of a commonly used term which I have some expertise with. We each came up with definitions, his got more into the implementation, I stayed at a high level and made an observation about the usage of the term. I will refrain from further detail; I just want to brag here, because one of those, "hey, you're a nerd, maybe you know how to describe this" questions made it into like a real, official, useful thing instead of just being a dumb argument over beer and turkey.

Hey, photo credit and a useful consultant on a matter! Great month, October!

And now I will go contemplate what a fricking small world tech and, er, related fields are.
