A
fast input/output (I/O) data transfer standard used for connecting peripherals
to a computer or controller. Typically, each device connected to a computer
uses its own port. USB can connect up to 127 peripherals through a single
port, and peripherals can be connected together. USB devices may be
hot plugged, which means that power does not have to be turned off to
connect or disconnect a peripheral. USB is becoming the primary means
of connection for printers and other peripherals to PCs, and is supported
by most major hardware, software and telecommunications providers.
