On laptops and desktops, a USB ii.0 port will ever exist Type-A, while on tablets and phones, it will likely be micro USB.

USB 3.0

USB iii.0

Also Known As: SuperSpeed USB, USB 3 Description: Nifty for external difficult drives, SSDs and high-res docking stations, USB three.0 has a maximum transfer charge per unit of five Gbps, more than x times that of its predecessor, USB 2.0. Ports for USB 3 are automatically backward-compatible with USB 2.0 cables and devices. USB iii ports on a reckoner use a rectangular, blazon-A connector and are normally indistinguishable from their older counterparts. Sometimes these SuperSpeed ports will have a light bluish colour or a tiny "SS" logo adjacent to them to indicate their higher transfer charge per unit, but not always.

USB 3.1 Gen 1

USB 3.ane Gen 1

Also Known As: USB three.1, SuperSpeed USB Clarification: USB 3.ane gen 1 is a connection protocol that's the same five-Gbps speed equally USB 3.0, but information technology works only on USB Blazon-C ports.
