USB port
Universal Serial Bus
port. A connector for plugging
in multiple, ultra-high-speed
peripherals. USB ports are
gradually replacing serial ports
and parallel ports and
eliminating the need for so many
connectors and cables. (Multiple
USB peripherals can be linked
together in a chain to share the
same port.) Windows 98
included a built-in driver for
USB peripherals. Windows
Millennium and Windows XP
support a new USB standard that
is 40 times faster than the
previous standard.
