VC Virtual Circuit
A connection from your DSL router to your ISP.
VCI Virtual Circuit Identifier
Together with the Virtual Path Identifier (VPI), the VCI
uniquely identifies a VC. Your ISP will tell you the VCI for
each VC they provide. See VC.
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 BT Micro, 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 BT Micro 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 all of the 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 BT Micro.
It provides improved data encryption and stronger user
authentication. The mode of WPA supported on your BT Micro
