USB+2.0

The acronym USB stands for Universal Serial Bus. A USB acts like a bus to guide what ever is being down loaded to the device it is connected to. The USB can also guide things from other devices to a computer. “The USB was designed to allow many peripherals to be connected using a single standardized interface socket.” This comes from [|www.Wikipedia.com]. This interface socket improves play and plug by allowing hot swapping. Hot swapping allows a device to run without shutting down or wasting its charge. A USB can be connected to many different devices. These devices are:
 * 1) mice
 * 2) keyboards
 * 3) PDA’s
 * 4) gamepads
 * 5) joysticks
 * 6) scanners
 * 7) digital cameras
 * 8) printers
 * 9) personal media players
 * 10) flash drives
 * 11) external hard drives
 * 12) personal computers
 * 13) video game consoles

Wikipedia.com says, “A USB system has an asymmetric design. It consists of a host. A host is a multitude of downstream USB ports. It also has multiple peripheral devices that are connected in a tiered-star topology.” Did you know that 127 different devices can be hooked up to a single host controller? That is so cool! To connect a webcam to the computer you must use a USB cord. A USB device uses a communication base called pipes. Pipes are connections from the host controller called logical channels. A USB can have up to 32 active pipes.
