User manual

Real - • RealAudio is a proprietary audio format developed by RealNetworks. It

uses a variety of audio codecs, ranging from low-bit rate formats that can be

used over dialup modems, to high-ﬁdelity formats for music. It can also be used

as a streaming audio format, that is played at the same time as it is downloaded.

It is used heavily by the BBC web sites.

SSID - • Service Set Identiﬁer, is a name used to identify the particular IEEE 802.11

wireless LAN’s to which a user wants to attach. A client device will receive

broadcast messages from all access points within range advertising their SSID’s,

and can choose one to connect to based on pre-conﬁguration, or by displaying

a list of SSID’s in range and asking the user to select one.

UPnP - • Universal Plug and Play is a set of computer protocols promulgated

by the UPnP Forum. The goals of UPnP are to allow devices to connect

seamlessly and to simplify the implementation of networks in the home (data

sharing, communications, and entertainment) and in corporate environments for

simpliﬁed installation of computer components. UPnP achieves this by deﬁning

and publishing UPnP device control protocols built upon open, Internet-based

communication standards.

WEP - • Wired Equivalent Privacy is a deprecated algorithm to secure IEEE 802.11

wireless networks. Wireless networks broadcast messages using radio and are

thus more susceptible to eavesdropping than wired networks. When introduced

in 1997, WEP was intended to provide conﬁdentiality comparable to that of a

traditional wired network.

WEP is often inaccurately referred to as Wireless Encryption Protocol.

Wi-Fi - • Wi-Fi is a trademark of the Wi-Fi Alliance, founded in 1999 as Wireless

Internet Compatibility Alliance (WICA), comprising more than 300 companies,

whose products are certiﬁed by the Wi-Fi Alliance, based on the IEEE 802.11

standards (also called Wireless LAN (WLAN) and Wi-Fi). This certiﬁcation warrants

inter operability between different wireless devices.

A Wi-Fi enabled device such as a PC, game console, mobile phone, MP3 player

or PDA can connect to the Internet when within range of a wireless network

connected to the Internet.

WMA - • Windows Media Audio is an audio data compression technology

developed by Microsoft. The name can be used to refer to its audio ﬁle format or

its audio codecs. It is a proprietary technology that forms part of the Windows

Media framework. WMA consists of four distinct codecs. The original WMA

codec, known simply as WMA, was conceived as a competitor to the popular

MP3 and RealAudio codecs.

WPA - • Wi-Fi Protected Access is a certiﬁcation program created by the Wi-Fi

Alliance to indicate compliance with the security protocol created by the Wi-Fi

Alliance to secure wireless computer networks.
