USB stands for Universal Serial Bus - as the name indicates, USB uses a similar protocol to the older serial technology (RS-232) that is still common on many devices today.

Since the technologies are so closely related you can actually buy adapters that will give you a true conversion from USB to serial (since many new computers don't come with serial ports if you want to use a serial device this is necessary).
