Windows XP
Microsoft Windows XP (Microsoft Windows NT 5) is the version of the Windows operating system from Microsoft that succeeded to Windows 2000 and Millennium. He was known by the codename Whistler during its development. The architecture of Windows XP is built on kernel NT 5.01, improved kernel Windows 2000 which is true for the general public.
The marketing of Windows XP held October 25, 2001. The OS has flooded the market through two versions, Windows XP Home Edition, Windows XP Professional Edition. Specific versions were born with a 64bit or even one for the tablet -PC.
WLAN
Wireless Local Area Network. Wireless LAN using radio waves to ensure the flow of information between machines (computers or peripheral) and interconnected.
WPA
Standard safety chosen by the manufacturers of materials to protect users against the risk of hacking wireless networks. He must replace the current system WEP (Wired Equivalent Privacy), deemed insufficient to protect businesses.
WPA works with all standards Wi-Fi Current: 802.11a, 802.11b, 802.11g and 802.11i.
WPA uses a new algorithm for encrypting data based on such a dynamic key management, which was lacking in WEP. It also implements a system for identifying users based on a server Central d 'Authentication. A special mode of WPA allows individuals to enjoy security without having the authentication server.
WUSB
Standard wireless link to replace the USB2 connection in many cases between devices and the computer or workstation.
WUSB (Wireless USB) Authorizes a range of 10 feet (5 meters cons USB), according to a flow theoretical varies depending on the distance (480 Mbit / s or 60 Mb / s at 3 meters, 110 Mbps at 10 meters). Adapters for using the WUSB on computers not equipped with native drivers can use USB2, the Compatibility have been preserved.
The connection is through a spectrum transmission very Broadband (UWB or Ultra Wide Band) spread between 3.1 and 10.6 GHz used by very short pulses, which guarantees low energy consumption (2 x less than USB2). It is therefore perfect coexistence with standard Bluetooth (2.4 GHz), and wireless LAN type 802.11a (5GHz), b and g (2.4 GHz). The bandwidth of WUSB is 480 Mbit / s (60MB / s) at a distance of 3 meters, and fits with the distance depending on the quality of transmission, to reduce to 110 Mbps at 10 meters.
The security of the wireless connection is secured by encryption type AES (Advanced Encryption Standard) 128-bit, based on a key exchange in which the code is determined when the first connection and prevent hackers from a post abroad.
