USB (Universal Serial Bus) Connector
The universal serial bus (USB) is an emerging serial interface standard for telephony and multimedia devices.
Each USB port is a single connector for devices that previously used serial, parallel, keyboard, mouse and game ports.
USB uses Plug and Play to determine which type of device has been attached to the connector.
Each USB device is accessed by a unique USB address.
A device called a hub is used to convert a single USB connector into multiple attachment points.
A hub has multiple ports where peripherals can be attached.
USB provides 12 megabits-per-second (Mbps) bandwidth with a maximum of 63 peripheral
devices, and a maximum signal distance of (16 ft.) five meters per segment.
(If more than one USB device is to be attached, the device must be connected to a hub.
The USB is compliant with Universal Host Controller Interface Design Guide 1.0.
