What's the difference between a computer salesman and a used-car salesman?
Over on Twitter, it was noted that you should never hesitate to ask what a computer salescritter means by a term he/she/it uses. He/she/it may not know.
Once upon a time, back when Babbage was a lad, I was considering buying a computer. A store had one that I was interested in, so I went to have a look. The salesman fastened onto me almost immediately, trotting out all kinds of stuff he considered selling points, and ending just about every stream of pitch-talk with "... and it's got two RS-232 ports!"
At the time, I didn't know what an RS-232 port was. (If you don't know, you might think of it as the USB of the day, except for being a lot harder to work with.) And didn't want to parade my ignorance. But I figured that if I didn't want to go on being ignorant, I'd better ask.
"What's an RS-232 port, and why would I want one?"
You'd have thought I'd hit him with a plank. He got a completely stunned, blank look on his face, and just stood there. "I don't know ..."
But not for long. Give him credit, his sales skills kicked in in a matter of seconds, and he came back with, "... but if you want one, we've got two!"

This assumes a lot, a sales person, even in security has a different set of motives than a practitioner.
Normally involving salary, monthly figures and often they are have a lot of pressure on their shoulders - which borders on bullying in the workplace. But often a lot of workplaces don't want to bring that subject at all, even openly.
