These are commonly known as micro or mini USB, because they are much smaller in size. The other end of the same cable that plugs into smaller devices such as portable hard drives, cameras and smartphones is called Type B connectors. The former is bigger and has a rectangular shaped connector which is plugged into laptops, desktops, game consoles.
In USB 2.0 and 3.0, there were two Types of connectors–Type A and Type B. There is no “this side up' requirement with Type-C, because both its ends have a reversible connector of same size and you can plug it in any which way. The primary difference between the old and the new standard is the design of the port, and subsequently the cable itself. Developed in the early 1990s, USB is not the trademark of any one company.
USB (Universal Serial Bus) is a cross platform technology that allows users to connect two devices, such as a smartphone with a PC, to either transfer data to or fro, or to charge the connected device. The OnePlus 2 smartphone, which will be available next month, will be the first Android phone to feature this new USB connection. This new standard will soon make its way to smartphones as well.
