Seems like nowadays everything has to have a fancy set of initials. Some folks just like to keep others confused. What the army used to call a bazooka is now an RPG (rocket propelled grenade). The military almost has its own secret language for everything from weapons to food. When you eat in the field you get an MRE (meal ready to eat).
In your field of computers, we deal with URLs, CPUs, USBs, and I'd have a hard time if I had to know all the sets of initials you probably have to know as a programmer. Trying to understand a doctor can be a nightmare.
In days gone by they'd at least turn sets of initials into an acronym: laser= light amplification by the stimulated emission of radiation, radar = radio detection and ranging, blimp = type B limp balloon (as opposed to dirigible with rigid frame), posh = port outbound / starboard home (cruise liner passengers who knew the best side of the ship to be on). Today we don't get a word, just a set of letters. Today, specialists in any field seem to speak their own language that others can't understand.
