computing is carried out. Bluetooth technology is capable of being transmitted at 721 Kbps
and is very popular with PDAs (personal digital assistants) such as the Palm Pilot and Visor.
Bluetooth transceivers are connected to the PC via a USB or serial port. Many devices
now come with built-in Bluetooth receivers and transmitters.
One advantage of Bluetooth technology is that the transmissions between Bluetooth
devices are encrypted and use frequency hopping (changing frequencies for each trans-
mission), which combine to provide privacy and security for the PC or PDA user.
