W
WEP (Wired Equivalent Privacy)
All 802.11b (Wi-Fi / wireless) networks use WEP
as their basic security protocol. WEP secures data
transmissions using 64-bit or 128-bit encryption;
however, it does not offer complete security and
is usually used in conjunction with other security
measures such as EAP.
Wi-Fi
Wi-Fi (Wireless Fidelity) is a wireless
technology brand owned by the Wi-Fi Alliance
intended to improve the interoperability of
wireless local area network products based
on the IEEE 802.11 standards. Common
applications for Wi-Fi include Internet and VoIP
phone access, gaming, and network connectivity
for consumer electronics such as televisions,
DVD players, and digital cameras.
WPA / WPA2 (Wi-Fi Protected Access)
A Wi-Fi standard that was designed to improve
upon the security features of WEP. The technology
is designed to work with existing Wi-Fi products
that have been enabled with WEP (i.e. as a
software upgrade to existing hardware), but the
technology includes two improvements over WEP.
WPS
Wi-Fi Protected Setup. A standard for easy
and secure establishment of a wireless home
network.
The goal of the WPS protocol is to simplify the
process of connecting any home device to the
wireless network, and so it was fi rst named
‘Wi-Fi Simple Confi g’. Also, the protocol is meant
to prevent home users from exposing their
networks to any sort of attack, and especially
free-loading onto their connection to the internet,
by confi guring the Wi-Fi Protected Access
parameters of the Network in an easy way.
X
xD Card
EXtreme Digital Picture Card. A fl ash memory
card used in digital cameras.
S
SD Card
Secure Digital Memory Card. A fl ash memory
card that provides storage for digital cameras,
cellphones and PDAs. SD Cards use the same
32 x 24mm form factor as the MultiMediaCard
(MMC), but are slightly thicker (2.1mm vs.
1.4mm), and SD Card readers accept both
formats. Cards up to 4GB are available.
SSID
Service Set IDentifi er. The name assigned to a
wireless Wi-Fi network. All devices must use
this same, case-sensitive name to communicate,
which is a text string up to 32 bytes long. Typically,
SSID is set to the name of the equipment vendor.
It can be manually changed by going into the
confi guration settings of the access point with a
Web browser. The client machines can identify all
the wireless networks that they fi nd when they
boot up, unless the networks are hidden.
T
TCP/IP
Transmission Control Protocol/Internet
Protocol. A communications protocol
developed under contract from the U.S.
Department of Defense to internet work
dissimilar systems. Invented by Vinton Cerf and
Bob Kahn, this de facto Unix standard is the
protocol of the Internet and the global standard
for communications.
U
UPnP
Universal Plug and Play. A family of protocols
from the UPnP Forum (www.upnp.org) for
automatically confi guring devices, discovering
services and providing peer-to-peer data
transfer over an IP network. UPnP is not
technically related to PnP (Plug and Play).
It is related by concept: both provide zero
confi guration, which is automatic installation
without manual confi guration.
