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 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.

WiFi

Wireless fidelity (pronounced y-phi) brand name applied to products supporting IEEE 802.11b.

Wireless Cable
