USB Electrical Interfaces are an important part of your computer system and the success of your computer. USB is a low-speed USB port, which has limited capacity to carry digital data. Some computers use USB ports to connect external devices to provide an audio output or transmit video information. Other computers use USB ports to connect internal devices such as printers or scanners. USB electrical connectors are with USB hubs.
Most of the USB devices used on a computer are compatible with the specific USB wiring scheme used by the computer manufacturer. The USB wiring scheme is a system designed by the USB Implementers Forum. The USB specification also defines the USB peripheral controller and some peripherals required to make it possible for a user to create a USB cable that is compatible with the operating system and hardware of the computer system.
