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 system 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 device.It provides improved data encryption and stronger user authentication. The mode of
WPA supported on your system 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.
