Since I don't have an IT or a computer science degree slapped onto me, I don't know everything there is to "tech lingo", but I do know quite a few advanced terms that a generic, everyday computer user who isn't tech-savvy might not know.
Yeah, I could consider myself.....85% familiar with tech lingo xD Back when I was attending school in San Diego, my classmates were extremely tech literate and surprisingly I could understand them. But when I'm explaining stuff to my parents or family members they're all like "mija, i canNOT understand a word you are saying".
I tend to have so much trouble "dumbing down" tech lingo for the ones that aren't familiar/don't know how technology works. Sometimes I wish everyone I knew was so on top of technology like I am, but alas it won't happen. xD
I know enough but nothing particularly technical. Condescending one's terminology is unnecessary (every educated person ought to be reasonably able to piece together what most 'long' words mean from their elemental constituents) and can be very misleading, but apparently that's just the way I think.
