The Desert Bird asked:
How does the data physically travel trough the USB? Electrons? Electron pulses? I can understand how electrical energy in a cable travel by means of electrons, but computer data??

I understand that a USB cable exist of 4 wires (2 for data travel, 1 for energy to power a device and 1 that act as a ground wire).
So are there a difference in what actually travels through the four wires?
