ABSTRACT
WAI (Web Accessibility Initiative) Level: 1 Definition: An effort launched by the World Wide Web Consortium in 1997 to raise awareness of, and develop technologies for, people with disabilities using the Internet. Because there are literally millions of people around the world with some form of disability or disabilities that make it difficult or impossible for them to use and participate in the development of the Internet, web accessibility has become a priority for those who oversee Internet development. Those involved in the Web Accessibility Initiative coordinate with various organizations around the world to improve the accessibility of the Web, paying special attention to the development of accessible technologies, creating accessibility guidelines and tools, promoting education and outreach, and conducting research and development. (See also Accessible Content.)
WAN (Wide Area Network) Level: 3 Definition: An extended communications network allowing data or other signals to be transmitted from a corporate or business LAN via the public telephone switched network or through a private alternative telecom service carrier to another business LAN at some distant location. WANs are different from LANs in that signals
through an whereas ally restricted to a single business or building. A common WAN application is to use a telephone RBOC or ALT carrier to interconnect to LANs located in two separate cities, such as Chicago and Indianapolis.
