Which types of connections can be used to connect a handheld PC to the Internet? (Select TWO.)
1. >>Bluetooth
2. Infrared
3. >>Cellular WAN
4. FireWire
Explanation : Cellular WAN is a technology that uses cell phone equipment to link a handheld PC, such as a Windows CE device or a Palm Pilot, to the Internet. A handheld PC is also called a Personal Digital Assistant (PDA). Cellular WAN has a transfer speed up to 56 kilobits per second (Kbps).
Bluetooth is a low-speed wireless technology for connecting devices in a personal area network. Bluetooth devices include mouse, keyboard, and digital cameras. The range for Bluetooth communication is only 100 meters. It operates at 721 Kbps. Some cell phones are equipped with Bluetooth to allow them to connect to other Bluetooth devices within range, including wireless headsets or wireless Internet access points. If you have a Bluetooth-enabled Internet access point, you can connect to the Internet using a Bluetooth-enabled device as long as you are within range.
FireWire (IEEE 1394) is a high-speed wired connection for connecting peripherals, such as video cameras, external hard drives, and printers. It is a wired technology, not a wireless technology. Two speeds are available: 400 megabits per second (Mbps) and 800 Mbps.
Infrared is a line of site wireless technology that supports transfer rates of 9600 bps to 4 Mbps. Its maximum range is 20 feet. It is typically used to connect a PDA to a PC or for supporting a wireless keyboard, mouse, or printer.
