These extra connections allow more data bandwidth, but also allow for signals to be sent and received simultaneously. This is due to four extra connector wires inside a USB cable. 3.0 can reach speeds over ten times faster at 4.8 Gbit/s. USB 2.0 ports are only able to reach a 480 Mbps transfer rate even over short, efficient connector wires. USB 3.0 is an advanced form of USB 2.0 with a faster transfer rate. On desktops, you can identify a type-A USB port, the traditional rectangle USB port shape, by its color. The original line of USB 1.0 ports is hard to find, but USB 2.0 and USB 3.0 are found nearly everywhere. Like any technology, the USB design has not stood still.
