USB stands for Universal Serial Bus. USB is a data transfer protocol that revolutionized the world of computer peripherals because it was much faster than previous parallel and serial ports. USB cables bear a trident-shaped symbol and can be used to connect almost any contemporary peripheral device (such as a printer, scanner or digital camera) to a computer, either directly or via a USB hub.
