As a consultant, one of the things i frequently have to do is translate geek speak into understandable terms for upper management. While “dropping your IIS box into a DMZ” means nothing to a lot of people, “segregating your Internet accessible web site from the rest of your network” is mildly better. Pervasive Computing has it right when they say:

…keep it simple. If you can’t explain it simply, you don’t understand it. Or you’ve just gotten lazy and rely on the jargon.

My Pop was also a big fan of the KISS method - Keep It Simple, Stupid!
