TERM DEFINITION
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 encr yption protects the privacy
of data transmitted over a WLAN. 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. Because WEP can be difficult to use
and does not provide very strong encryption, Motorola
recommends using WPA if possible.
WiFi
Wireless fidelity (pronounced y-phi) brand name applied to
products supporting IEEE 802.11b.
Wireless Cable
Modem
Gateway
The Motorola SURFboard Wireless Cable Modem Gateway is a
single device that combines a cable modem, router, Ethernet
switch, wireless access point, and DHCP 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.
WPA
Wi-Fi Protected Access (WPA) encr yption, as described
on the Wi-Fi Alliance web pa
. It
is a far more robust form of encryption than WEP. Motorola
recommends using WPA if all of your client hardware supports
WPA.
