Is there a difference in USB ports for example type A USB port?

Their are different types of usb ports. The oldest one is USB1, then comes USB2 which is now mostly used and just out is USB3 but that isn't used by a lot of people at this moment.

Type A and Type B refer to a type of plug on the end of a USB Cable.

USB 2.0 and 3.0 are protocol shifts, 3.0 has some additional hardware behind the cables and 1.0 and 2.0 are identical cable wise. 3.0 is backwards compatible with 1.0 and 2.0.
