USB, that little rectangular plug that can be found on just about every computer peripheral cable you come across, is one of the biggest success stories in the history of computing. Ditching the slow serial and parallel cables of yore and replacing them with a fast, universal standard that could draw power and allowed connecting of dozens of peripherals without rebooting... well, it was genius. When USB 2.0 arrived, with much faster performance, it got even better. It's not hyperbole to say that USB, despite its humble status as a mere connector, is one of the most important computer technologies to ever be invented.
