VPI
Virtual Path Identifier
Together with the Virtual Circuit Identifier (VCI), the VPI uniquely identifies
a VC. Your ISP will tell you the VPI for each VC they provide. See VC.
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.
It provides improved data encryption and stronger user authentication.
The mode of WPA supported on your device is called Pre-Shared Key
(PSK), which allows you to manually enter a type of key called a pass
phrase.
WWW
World Wide Web
Also called (the) Web. Collective term for all web sites anywhere in the
world that can be accessed via the Internet.
