The Derivation of Usb
USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.It is currently developed by the USB Implementers Forum .
USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as parallel ports, as well as separate power chargers for portable devices.
Micro usb cable is usually used in Android Smartphone, like Samsung, Xiaomi, Huawei etc. its mainly function is data transferring and charging. One side is a micro connector, the other side is a usb 2.0 connector.
