U-Z

UDP	User Datagram Protocol
unicast	A point-to-point data transmission sent from one sender to one receiver. This the normal way you
	access websites. See also broadcast and multicast.
upstream	In a cable data network, upstream describes the direction of data sent from the subscriber computer
	through the cable modem to the CMTS and the Internet.
USB	Universal Serial Bus is a computer interface for add-on devices such as printers, scanners, mice,
	modems, or keyboards. USB supports data transfer rates of 12 Mbps and plug-and-play installation.
	You can connect up to 127 devices to a single USB port.
UTP	unshielded twisted pair (wire)
VLAN	A virtual local area network is group of devices on different LAN segments that are logically configured
	to communicate as if they are connected to the same wire.
VoIP	Voice over Internet Protocol is a method to exchange voice, fax, and other information over the
	Internet. Voice and fax have traditionally been carried over traditional telephone lines of the PSTN
	using a dedicated circuit for each line. VoIP enables calls to travel as discrete data packets on shared
	lines. VoIP is an important part of the convergence of computers, telephones, and television into a
	single integrated information network.
VPN	A virtual private network is a private network that uses “virtual” connections (tunnels) routed over a
	public network (usually the Internet) to provide a secure and fast connection; usually to users working
	remotely at home or in small branch offices. A VPN connection provides security and performance
	similar to a dedicated link (for example, a leased line), but at much lower cost.
WAN	A wide-area network provides a connection over a large geographic area, such as a country or the
	whole world. The bandwidth depends on need and cost, but is usually much lower than for a LAN.
WAP	Wireless access point or Wireless Access Protocol. See also access point.
WECA	The Wireless Ethernet Compatibility Alliance is a trade organization that works to ensure that all
	wireless IEEE 802.11b Wi-Fi devices — computer cards, laptops, air routers, PDAs, etc — can
	communicate with each other.
WEP	Wired Equivalent Privacy encryption protects the privacy of data transmitted over a wireless LAN.
	WEP uses keys to encrypt and decrypt transmitted data. The access point must authenticate a client
	before it can transfer data to another client. WEP is part of IEEE 802.11b.
Wi-Fi	Wireless fidelity (pronounced y-phi) brand name applied to products supporting IEEE 802.11b.
Wireless Cable	The Motorola SBG1000 Wireless Cable Modem Gateway is a single device that combines a cable
Modem	modem, router, Ethernet switch, wireless access point, HPNA connection, print server, and DHCP
Gateway	server for SOHO or SME use.
WLAN	wireless LAN
world wide web	An interface to the Internet that you use to navigate and hyperlink to information.
