From Wikipedia, the free encyclopedia

Windows Vista is the name of the next version of Microsoft Windows, a proprietary graphical operating system used on personal computers, including home and business desktops, notebook computers, and media centers. Prior to the announcement of the Vista name on July 22, 2005, it was known by its codename Longhorn. As of September 2006, Windows Vista is at release candidate stage; Microsoft has stated the scheduled release dates for Windows Vista are currently November 2006 for business editions, and January 2007 for consumer editions.[1] These release dates come more than five years after the release of Windows XP, Microsoft's current consumer and business operating system, making it the longest time span between releases of Windows.
Windows Vista has hundreds of new features, some of the most significant of which include an updated graphical user interface and visual style dubbed Windows Aero, improved searching features, new multimedia creation tools such as Windows DVD Maker, and completely redesigned networking, audio, print, and display sub-systems. Vista also aims to increase the level of communication between machines on a home network using peer-to-peer technology, making it easier to share files, password settings, and digital media between computers and devices. For developers, Vista introduces version 3.0 of the .NET Framework, which aims to make it significantly easier for developers to write high-quality applications than with the traditional Windows API.
Microsoft's primary stated goal with Vista, however, has been to improve the state of security in the Windows operating system.[2] One of the most prevalent common criticisms of Windows XP and its predecessors are their commonly exploited security vulnerabilities and overall susceptibility to malware, viruses and buffer overflows. In light of this, then Microsoft chairman Bill Gates announced in early 2002 a company-wide 'Trustworthy Computing initiative' which aims to incorporate security work into every aspect of software development at the company. Microsoft claimed it prioritized improving the security of Windows XP and Windows Server 2003 above finishing Windows Vista, significantly delaying its completion.[3]

WiMAX - Wikipedia, the free encyclopedia

WiMAX - Wikipedia, the free encyclopedia: "WiMAX is defined as Worldwide Interoperability for Microwave Access by the WiMAX Forum, formed in April 2001 to promote conformance and interoperability of the IEEE 802.16 standard, officially known as WirelessMAN. The Forum describes WiMAX as 'a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL'.
'WiMAX is not a technology, but rather a certification mark, or 'stamp of approval' given to equipment that meets certain conformity and interoperability tests for the IEEE 802.16 family of standards. A similar confusion surrounds the term Wi-Fi (Wireless Fidelity), which like WiMAX, is a certification mark for equipment based on a different set of IEEE standards from the 802.11 working group for wireless local area networks (WLAN). Neither WiMAX, nor Wi-Fi is a technology but their names have been adopted in popular usage to denote the technologies behind them. This is likely due to the difficulty of using terms like 'IEEE 802.16' in common speech and writing.' - OECD [1]"

W-CDMA - Wikipedia, the free encyclopedia

W-CDMA (Wideband Code Division Multiple Access) is a type of 3G cellular network. W-CDMA is the technology behind the 3G UMTS standard and is allied with the 2G GSM standard with the International Telecommunication Union - ITU.
More technically, W-CDMA is a wideband spread-spectrum 3G mobile telecommunication air interface that utilizes code division multiple access (or CDMA the general multiplexing scheme, not to be confused with CDMA the US standard).
