USB is an emerging technology in which only two connector types are used for all devices that
previously used serial, parallel, keyboard, mouse, and game ports. A PC designed with USB architecture includes a host controller and one or more USB connector ports.
The USB contains two connector types - A and B. All USB ports on your PC will be of Type A. Type A is also used on those devices in which the external cable is permanently attached, such as
keyboards and mice. Type B is used in applications which require detachable external cable such as printers, scanners and modems. A Type A/B cable is used to connect these devices to a hub
(distribution box) and to connect the hub directly to your PC. |
