Lo que comenz\u00f3 como un simple reemplazo para los puertos serie y paralelo en 1996 se ha transformado en la columna vertebral digital de la inform\u00e1tica moderna, gestionando desde la transferencia de datos y la carga de dispositivos hasta la transmisi\u00f3n de v\u00eddeo y la conectividad de red.\r\n <\/p>\r\n\r\n <p class=\"usb-text-paragraph\">\r\n La confusi\u00f3n surge de la naturaleza estratificada de la tecnolog\u00eda USB.
