WAN
Wide Area Network
Any network spread over a large geographical
area, such as a country or continent. With respect
to the device, WAN refers to the Internet.
Web browser
A software program that uses Hyper-Text Transfer
Protocol (HTTP) to download information from
(and upload to) web sites, and displays the
information, which may consist of text, graphic
images, audio, or video, to the user. Web browsers
use Hyper-Text Transfer Protocol (HTTP). Popular
web browsers include Netscape Navigator and
Microsoft Internet Explorer. See HTTP, web site,
WWW.
Web page
A web site file typically containing text, graphics
and hyperlinks (cross-references) to the other
pages on that web site, as well as to pages on
other web sites. When a user accesses a web site,
the first page that is displayed is called the home
page. See hyperlink, web site.
Web site
A computer on the Internet that distributes
information to (and gets information from) remote
users through web browsers. A web site typically
consists of web pages that contain text, graphics,
and hyperlinks. See hyperlink, web page.
WEP
Wired Equivalent Privacy (WEP) encrypts data
over WLANs. Data is encrypted into blocks of
either 64 bits length or 128 bits length. The
encrypted data can only be sent and received by
users with access to a private network key. Each
PC on your wireless network must be manually
configured with the same key as your device in
order to allow wireless encrypted data
transmissions. Eavesdroppers cannot access your
network if they do not know your private key. WEP
is considered to be a low security option.
Wireless
Wireless is a term used to describe
telecommunications in which electromagnetic
waves (rather than some form of wire) carry the
signal over part or the entire communication path.
See wireless LAN.
Wireless LAN
A wireless LAN (WLAN) is one in which a mobile
user can connect to a local area network (LAN)
through a wireless (radio) connection. A standard,
IEEE 802.11, specifies the technologies for
wireless LANs.
WPA
Wi-Fi Protected Access
WPA is an initiative by the IEEE and Wi-Fi Alliance
to address the security limitations of WEP. WPA
provides a stronger data encryption method
(called Temporal Key Integrity Protocol (TKIP)). It
runs in a special, easy-to-set-up home mode
called Pre-Shared Key (PSK) that allows you to
manually enter a pass phrase on all the devices in
your wireless network. WPA data encryption is
based on a WPA master key. The master key is
derived from the pass phrase and the network
name (SSID) of the device.
