|Its just a type of USB plug;|
USB currently exists in three stages: 1.0, 1.1, and the high-speed 2.0. The original USB rev. 1.0 was relatively slow, pulling in 1.5 Mpbs. Revision 1.1, first widespread USB release, jumped up to a hefty 12 Mbps. Looking around the peripheral market nowadays, you will notice the common advertisement of USB devices and cables as ‘High-Speed USB’, which means that these products meet the specifications of USB 2.0.
USB 2.0, by now the most common interface around, boasts theoretical speeds of up to 480Mbps.
It has nothing to do with internet.
