The hottest technology in personal computing is wireless networking, which allows users to share a high –speed Internet connection among multiple computers without being tethered to wires or wall jacks. Known as WI-FI, this wireless system is commonly used to connect computers in various rooms of a home, but it’s also popping up in public houses like airports, hotel lobbies and coffee shops.
The Mobile Internet relies on a new set of standards, known as the Wireless Application Protocol (WAP). The existing technology will provide efficient access to information and services from a wide range of mobile devices. In particular, WAP extends the Internet by addressing the unique requirements of the wireless network environment and the unique characteristics of the small handheld devices.
