Ever thought of the different shapes and sizes of USB ports and connectors? These are actually the types of USB in which each have their own purpose for effective use and of course, easier user-recognition. Definitions USB Type-A Most commonly seen at the other end of a standard USB Type-A cable and it is usually plugged onto different peripheral devices (a printer, phones, external hard drives and so on). Same as with your Type-A, the ends are called B- male while the port on the peripheral device where you plug the connector is called the B-female. What’s the difference between a USB Type-A and USB type-B? Aside from their pin configurations, they also have different shapes and sizes. These shapes are designed to comply with different peripherals with different sizes. Take a smart phone for example – most of the phones used these days are capable of re-charging through the use of cable connectors, but to be effective, a small Male-connector should be used to fit the standard thinness of a phone. Known as your standard-A, a USB Type-A is the first original design for a USB port that has a flat and rectangular shape. It is mainly used to connect and control other USB devices such as saving data on external storage devices and using a mouse and keyboard. Usually with port connections, you’ll have the male and female part and in this case, we have your A-male connector and A-female connector. A-male connector is the end part of a typical USB connector/cable and A-female connector is the USB port which the A-male connector/cable goes into. A USB Type-A is mostly intended for host devices (desktop computers, laptops, game consoles, media players and so on). A type-A connector will also be always compatible with a Type-A port even if the device and the host uses different USB versions like your USB 3.0 and USB 2.0 port and vice versa. However, USB 2.0 hosts may use the USB 3.0 port, but it can’t use the features of the USB 3.0 like having a faster transfer rate.
