I work for a music recording company, so I hear technical jargon all the time. Not just the usual stuff like hard drive and RAM, I hear some pretty serious stuff like DMX-4 and 24-80’s and all kinds of stuff with numbers and letters. And that’s just the beginning.
Of course, with myself being a graphic designer, I have my own jargon. But I try to refrain from using it, because the last time I did somebody thought I called them a dingbat.
