Wireless Fidelity
 Wi-Fi, or wireless fidelity
is commonly used in business and home high-frequency
wireless local area networks, or WLAN's. Wi-Fi is
growing in popularity as an alternative to wired local
area networks (LAN's).
Bluetooth, another wireless technology, can also be used for
computers to communicate with each other, though it is more
restrictive because it is low-frequency and thus covers less
area. Bluetooth is commonly used in conjunction with the
updating of Personal Digital Assistant (PDA) scheduling
calendars.
Apple AirPort (for Mac) is another wireless technology in
use today.
When using wireless technology, be mindful to use security
measures. Unprotected signals can be easily intercepted. That
means all information on your hard drive can be accessible by
remote intruders. While a WLAN cannot be completely secured,
there are measures that can be taken to lessen the risk.
