NA (Not an Acronym)
Silly Brian, the NT in Windows NT only stands for “New Technology” if you’re in the marketing department of Microsoft. NT was slang for N-Ten, the code name for the Intel’s next big processor (circa 1988), which the OS was originally intended for. Sometime after it became Windows NT, some MBA decided it should stand for New Technology. While it’s been suggested that it was chosen because WNT is a character-by-character increment of VMS, which is the grandfather of Redmond’s modern OS, I’m not buying it because it was originally named OS/2 NT.
Meanwhile, Apple insisted that the AV in Quadra AV machines (with audio and video DSPs) was just a cool sounding moniker and by no means stood for anything and Sun has declared that JDBC is just a four-letter trademark and not an acronym. Someone needs to tell Sun that Google doesn’t forget.
