Wireless networking allows computers to access the Internet without physically connecting to it with cables. Wi-Fi, short for "wireless fidelity," is a compatibility standard for wireless networking that's used in the creation of home and public networks.
Instead of using a cable to transmit data, a computer can communicate with the Net through radio waves. If you've always wanted to surf the Web from bed or wished that you could get online while poolside, a wireless network in your home and a wireless-enabled computer could be for you.
- The Web has practical resources with tutorials for establishing home wireless networks.
- A few sites have directories that list Wi-Fi "hotspots." These are public locations where computers can access the Web through open Wi-Fi networks. Knowing where to find hotspots makes connecting to the Net while on the go much easier to do.
