USB is a connectivity specification developed by the USB Implementers Forum that provides a single,
simple, standardized way to connect up to 127 devices to a computer. USB shielded cables contain two
wires for power +5 volts (red) and ground (brown) and a twisted pair of wires (yellow and blue) that carry
data. The USB standard supports data transfer rates of 12 Mbps (megabits per second). USB devices can
be connected or disconnected without restarting the computer. Two USB 2.0 Type A female USB 2.0 ports
for keyboard, mouse and external storage devices.
