World Wide Web Internet
Internet (INTERNET) to provide HTML file services system generated by the HTML document often referred to as web pages (WEB PAGE), the user browser (BROWSER) to read and link.

WORM Write Once
CD-R as a call that can only be written once, but can be read many times the features. Worm lower case, that means can be automatically replicated, self-reproduction, usually a destructive force roaming on the networks and independent programs on yards. The first worm only by Xerox PARC (Xerox Paluoyatuo Research Center), two researchers writing in 1980, its name taken from John Brunner's 1975 sci-fi novel "waves Knight" (The Shockwave Rider), the name program for the tapeworm. November 1988, Robert T. Morris internet worm is almost a network to crash. Worm world's information is more friendly "worms" can be used as retrieval network, compiling URL (usually resource-bit standard) and reference tools.

WPA Wi-Fi Protected Access specification
By the Wi-Fi Alliance and IEEE working together to deliver enhanced versions of Wi-Fi security specification to replace the existing, but less secure WEP standard.
Wi-Fi products are now more than the so-called WEP encryption mechanism used to provide wireless Internet security, but WEP encryption mechanism is not strong, even if activated WEP, hackers, or data can be cracked within hours. WPA is based on the implementation of software upgrades on the hardware, the future will be compatible with the IEEE 802.11i standard. WPA security specification in the data on the safety of the major two more points: enhanced data encryption security, and providing the user login authentication. The former in the current very weak in WEP, the latter in the WEP is completely missing. WPA using TKIP (Temporal Key Intergrity Protocol) data encryption agreement to make up for all the known shortcomings of WEP. In addition, log in, WPA built-in 802.1x and EAP (extended sign the agreement), the user to log network must go through a central server before certification. WPA will be the future of the Association is also being prepared with the IEEE in the IEEE 802.11i security specification compatibility. WPA in the draft 802.11i standard is only a small part. WPA addresses the security needs of enterprises currently meet the urgent needs facing the WALN. In enterprise IT environments, WPA must be a server (eg RADIUS) with the use of in order to provide a central co-ordination type of log and management.
