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 so many 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
supports a new USB standard that is
40 times faster than the previous standard.
See serial port and parallel port.
See also peripheral.
Usenet (users' network) A world-wide
network of computers set up to transmit
messages to newsgroups. See newsgroups.
V.90 standard A standard adopted

modem does not conform to the V.90
standard, you can visit the manufacturer's
Web site and download a software
upgrade.)
