Universal Serial Bus (USB)
A standard specification governing the connection between a physical device (e.g., mouse, keyboard) to a controller, usually a computer system.
Universal Serial Bus (USB) specifications are designed simplify connecting peripherals to a computer, as well as supporting rapid transfer of data. There are currently three USB standards in use, 1.1, 2.0 and 3.0, which support data speeds of up to 12 Mbps, 480 Mbps and 5 Gbps, respectively.
USB is the successor to earlier, more complex versions of serial and universal physical ports. A physical port on a device that complies with the USB standard is usually referred to as a 'USB port'.
